The choice depends on whether you are studying IRS1 (insulin receptor substrate 1)'s role as the principal insulin/IGF-1 signaling scaffold or modeling its functions in insulin resistance and metabolic disease. The Knockout line is the standard tool for asking whether IRS1 is required for these processes — IRS1 is tyrosine-phosphorylated by the activated insulin receptor (INSR) and IGF-1R kinase, recruiting PI3K p85, GRB2, and other SH2-domain proteins to drive PI3K-AKT and other downstream pathways. Overexpression is useful for studying IRS1 in heterologous expression contexts. Important consideration: IRS2 paralog expression analysis is essential given functional overlap. This product complements the parallel INSR Knockout in HAP1 (also available) for upstream-downstream insulin signaling pathway dissection. Rescue with wild-type or Y608F/Y628F/etc. phospho-resistant IRS1 enables structure-function studies. The knockout is valuable for studying serine kinase-mediated IRS1 inhibition (mTORC1, JNK, S6K1 phosphorylate IRS1 at serine residues to inhibit insulin signaling) in insulin resistance research.

Yes. IRS1 rescue experiments require attention to scaffolding architecture: • Construct design: use a codon-modified IRS1 sequence with a small C-terminal tag (FLAG, HA). IRS1 has N-terminal PH and PTB domains (INSR/IGF1R interaction), and large C-terminal region with multiple tyrosine phosphorylation sites (YxxM motifs for PI3K p85 binding) and serine sites (negative regulation) — preserve all elements. • Phospho-tyrosine-resistant rescue: Y608F, Y628F, Y939F mutations in PI3K-binding YxxM motifs abolish PI3K recruitment. • Phospho-serine-resistant rescue: S307A, S612A mutations remove inhibitory serine phosphorylation sites, generating constitutively active IRS1. • Functional readout: rescue should restore insulin/IGF-1-induced phospho-IRS1 (Y608), PI3K recruitment, and phospho-AKT. HAP1-specific considerations: • Diploidization: HAP1 cells gradually diploidize during extended culture — confirm ploidy by flow cytometry at the time of phenotypic assay. • Integration site sensitivity: position effects on transgene expression are more pronounced in near-haploid backgrounds; generating multiple independent rescue clones is strongly recommended. • Transduction efficiency: HAP1 transduces with lentivirus at moderate efficiency — increase MOI compared to standard immortalized lines.

The choice depends on whether you are studying HIF1A's role as the principal hypoxia-inducible transcription factor in a high-transfection-efficiency mechanistic platform. The Knockout line is the standard tool for asking whether HIF1α is required for hypoxic gene induction — HIF1α is the oxygen-regulated subunit of HIF; under normoxia, prolyl hydroxylases (PHD1/2/3) hydroxylate HIF1α at P402/P564, targeting it for VHL-mediated polyubiquitination and proteasomal degradation; under hypoxia, HIF1α stabilizes and binds HRE to drive expression of glycolytic enzymes, VEGF, EPO, and other hypoxic adaptation genes. Overexpression is useful for studying HIF1α gain-of-function effects. For systematic HIF1α biochemistry, the EDITGENE HIF1A Knockout in HEK293T is a workhorse mechanistic platform — HEK293T's very high transfection efficiency supports structure-function studies. This product complements the parallel HIF1A Knockout in HaCaT (also available); HEK293T is preferred for biochemistry and structure-function studies, HaCaT for skin biology and wound healing research. HIF2α (EPAS1) paralog expression analysis aids interpretation given partial functional overlap. Rescue with wild-type, hydroxylation-resistant (P402A/P564A double mutation = constitutively stable HIF1α), or DNA-binding-deficient HIF1α enables comprehensive structure-function studies. The knockout is critical specificity control for PHD inhibitors (roxadustat, daprodustat, vadadustat).

The choice depends on whether you are studying KMT2C (MLL3, ALR)'s role as a H3K4 monomethyltransferase at enhancers or modeling KMT2C-mutation-associated cancers and Kleefstra syndrome 2. The Knockout line is the standard tool for asking whether KMT2C is required for these processes — KMT2C is the catalytic subunit of the COMPASS-like complex (with PTIP, NCOA6, PA1, UTX/KDM6A, ASH2L, RBBP5, WDR5, DPY30) that deposits H3K4me1, the principal enhancer mark. Overexpression is useful for studying KMT2C in heterologous expression contexts. For cancer epigenetics research, the EDITGENE KMT2C Knockout in HAP1 is highly informative — KMT2C is one of the most frequently mutated genes in human cancers (loss-of-function in breast, bladder, lung, and many other cancers), functioning as a tumor suppressor. Rescue with wild-type or catalytically-dead KMT2C is the standard specificity control. The knockout is valuable for studying enhancer biology, KMT2C-mutant cancer dependencies, and emerging epigenetic therapy approaches — KMT2C-mutant cancers may show synthetic lethality with KDM5 (H3K4me-erasers) inhibition.

Yes, with considerations for KMT2C's large size: • Construct design: KMT2C encodes a very large protein (~5,000 aa) — full-length cDNA (~14 kb) rescue is technically challenging. Use codon-modified KMT2C with a small C-terminal tag (FLAG, HA); preserve SET domain (H3K4 methyltransferase activity), PHD fingers (chromatin reader), and FYRN/FYRC motifs. • Catalytically-dead rescue: SET domain catalytic residue mutations abolish methyltransferase activity and serve as the standard specificity control. • Domain-focused rescue: SET-containing C-terminal fragments are sometimes used when full-length rescue is impractical — these can be functional for enhancer methylation. • Functional readout: rescue should restore H3K4me1 levels at KMT2C target enhancers measured by ChIP-seq. HAP1-specific considerations: • Diploidization: HAP1 cells gradually diploidize during extended culture — confirm ploidy by flow cytometry at the time of phenotypic assay. • Integration site sensitivity: position effects on transgene expression are more pronounced in near-haploid backgrounds; generating multiple independent rescue clones is strongly recommended. • Transduction efficiency: HAP1 transduces with lentivirus at moderate efficiency — increase MOI compared to standard immortalized lines.

The choice depends on the experimental question. ILKAP (ILK-associated phosphatase, integrin-linked kinase-associated serine/threonine phosphatase 2C) is a PP2C-family protein phosphatase with characterized interactions with integrin-linked kinase (ILK). The Knockout line is appropriate for asking whether ILKAP is required for predicted phosphatase activities — ILKAP dephosphorylates ILK and antagonizes ILK-mediated signaling, with reported roles in GSK3β regulation and tumor suppression. Overexpression is useful for studying ILKAP gain-of-function effects. For ILK signaling research, the EDITGENE ILKAP Knockout in HAP1 provides a clean genetic background for characterizing ILKAP-specific functions. Rescue with wild-type or catalytically-dead (PP2C active site mutations affecting Mg²⁺ coordination) ILKAP is the standard specificity control. The knockout is valuable for studying ILK-ILKAP regulatory dynamics and emerging ILKAP-related signaling biology.

Yes. ILKAP rescue experiments require attention to PP2C architecture: • Construct design: use a codon-modified ILKAP sequence with a small C-terminal tag (FLAG, HA). ILKAP has the canonical PP2C phosphatase domain — preserve catalytic Mg²⁺-binding residues. • Catalytically-dead rescue: PP2C active site mutations affecting Mg²⁺ coordination abolish phosphatase activity and serve as the standard specificity control. • ILK-binding-deficient rescue: ILK-interaction surface mutations enable separating ILK partnership from intrinsic catalytic activity. • Functional readout: rescue should restore ILKAP-dependent ILK substrate dephosphorylation. HAP1-specific considerations: • Diploidization: HAP1 cells gradually diploidize during extended culture — confirm ploidy by flow cytometry at the time of phenotypic assay. • Integration site sensitivity: position effects on transgene expression are more pronounced in near-haploid backgrounds; generating multiple independent rescue clones is strongly recommended. • Transduction efficiency: HAP1 transduces with lentivirus at moderate efficiency — increase MOI compared to standard immortalized lines.

The choice depends on whether you are studying LIMK2 (LIM kinase 2)'s role in actin cytoskeleton dynamics via cofilin phosphorylation or its functions in cell migration and cancer biology. The Knockout line is the standard tool for asking whether LIMK2 is required for these processes — LIMK1 and LIMK2 phosphorylate cofilin/ADF at S3, inactivating their actin-severing activity and stabilizing F-actin. LIMK kinases function downstream of Rho-ROCK and Rac-PAK signaling. Overexpression is useful for studying LIMK2 gain-of-function effects. Important consideration: LIMK1 and LIMK2 share substantial substrate scope as cofilin kinases — single LIMK2 knockout may show modest phenotypes if LIMK1 compensates. Rescue with wild-type or kinase-dead LIMK2 is the standard specificity control. The knockout is a critical specificity tool for LIMK inhibitors (LIMK-i3 and emerging compounds) in cancer drug development — LIMK kinases have emerged as targets for limiting cancer cell migration and metastasis.

Yes. LIMK2 rescue experiments require attention to kinase domain architecture: • Construct design: use a codon-modified LIMK2 sequence with a small C-terminal tag (FLAG, HA). LIMK2 has N-terminal LIM domains, PDZ domain, and C-terminal kinase domain — preserve all elements. • Kinase-dead rescue: ATP-binding lysine mutation abolishes catalytic activity and serves as the standard specificity control. • Constitutively active rescue: T505E mutation (mimic of ROCK/PAK activation loop phosphorylation) generates constitutively active LIMK2. • Functional readout: rescue should restore phospho-cofilin (S3) levels and F-actin stabilization. HAP1-specific considerations: • Diploidization: HAP1 cells gradually diploidize during extended culture — confirm ploidy by flow cytometry at the time of phenotypic assay. • Integration site sensitivity: position effects on transgene expression are more pronounced in near-haploid backgrounds; generating multiple independent rescue clones is strongly recommended. • Transduction efficiency: HAP1 transduces with lentivirus at moderate efficiency — increase MOI compared to standard immortalized lines.

The choice depends on whether you are studying combined IP3 receptor function for ER Ca²⁺ release or distinguishing IP3R-mediated calcium signaling from IP3R-independent processes. The Triple Knockout line is uniquely valuable for asking whether IP3R-mediated calcium release is required for these processes — ITPR1, ITPR2, and ITPR3 are three functionally redundant IP3-gated Ca²⁺ release channels on the endoplasmic reticulum membrane. Single or double knockouts retain residual IP3R activity from the remaining paralog(s); triple knockout completely eliminates IP3R-mediated ER Ca²⁺ release. Single-isoform rescue (ITPR1, ITPR2, or ITPR3 alone) in the triple knockout enables isoform-specific functional dissection — the gold-standard experimental design for ITPR family. For calcium signaling research, the EDITGENE ITPR1/2/3 Triple Knockout in HEK293 is the gold-standard genetic tool — combined loss is required to eliminate IP3R-mediated Ca²⁺ release given the substantial functional overlap among the three isoforms. Single-isoform rescue is the gold-standard experimental design for distinguishing isoform-specific functions. The triple knockout is a critical specificity control for IP3R modulators (xestospongins, 2-APB) and is invaluable for studying Ca²⁺ store-dependent processes (mitochondrial Ca²⁺ uptake, ER-mitochondria contact sites, autophagy regulation) in a clean IP3R-null background.

Yes, and rescue experiments are uniquely powerful in this triple knockout: • Single-isoform rescue: re-introduction of ITPR1, ITPR2, or ITPR3 alone in the triple knockout enables isoform-specific functional dissection — the gold-standard experimental design for redundant IP3R family members. • Construct design: each ITPR isoform encodes a very large protein (~2700-3000 aa) — full-length cDNA rescue (~9 kb) is technically demanding. Use codon-modified sequences with small C-terminal tags (FLAG, HA); preserve IP3-binding region, central regulatory domain, and C-terminal channel domain with six transmembrane spans. • Channel-dead rescue: pore-loop residue mutations abolish Ca²⁺ permeation and serve as the standard specificity control for any single isoform rescue. • IP3-binding-deficient rescue: N-terminal IP3-binding domain mutations enable separation of IP3-induced versus constitutive Ca²⁺ release. • Functional readout: rescue should restore IP3-induced ER Ca²⁺ release measured by Ca²⁺ imaging (Fura-2, GCaMP6) following Gq-coupled GPCR stimulation or IP3 photorelease. HEK293 transduces efficiently with lentivirus and supports systematic isoform-specific rescue experiments.

The choice depends on whether you are studying Clec1a (C-type lectin receptor 1a)'s role as a dendritic cell C-type lectin receptor or modeling its functions in DC biology and pathogen recognition. The Knockout line is the standard tool for asking whether Clec1a is required for predicted activities — Clec1a is a member of the Dectin-1 cluster of C-type lectin receptors expressed on DCs and other myeloid cells, with emerging roles in DC homeostasis, vascular biology, and pathogen recognition. Overexpression is useful for studying Clec1a in heterologous expression contexts. For DC immunobiology research, the EDITGENE Clec1a Knockout in DC2.4 is highly relevant — DC2.4 is a murine bone marrow-derived dendritic cell line, providing a physiologically relevant context for Clec1a study. Other Dectin-cluster C-type lectin receptor expression analysis aids interpretation. Rescue with wild-type Clec1a is the standard specificity control. The knockout is valuable for studying DC C-type lectin receptor biology and emerging DC-targeted immunotherapy approaches.

Yes. Clec1a rescue experiments require attention to C-type lectin receptor architecture: • Construct design: use a codon-modified Clec1a sequence with a small intracellular C-terminal tag (FLAG, HA). Clec1a has extracellular C-type lectin domain (CTLD), single transmembrane span, and short cytoplasmic tail — preserve membrane topology. • Surface localization validation: confirm plasma membrane localization by cell surface staining before functional assays. • Functional readout: rescue should restore Clec1a-dependent phenotypes identified during knockout characterization. DC2.4-specific considerations: • DC2.4 is a murine bone marrow-derived dendritic cell line (C57BL/6 origin, immortalized with myc/raf retrovirus) — widely used as a continuous murine DC model for antigen presentation and DC immunobiology research. • Lentiviral transduction is supported with moderate efficiency. • DC2.4 retains key DC features including MHC class I/II expression and TLR responsiveness; characterize basal DC marker profile before phenotypic assays.

The choice depends on whether you are studying CTNNB1 (β-catenin)'s role as the principal effector of canonical Wnt signaling or modeling β-catenin-mutant cancers and developmental disorders. The Knockout line is the standard tool for asking whether β-catenin is required for these processes — β-catenin has dual functions: structural (E-cadherin-mediated cell-cell adhesion at adherens junctions) and signaling (canonical Wnt pathway effector); in the absence of Wnt, β-catenin is targeted by the destruction complex (APC, AXIN, GSK3β, CK1α) for proteasomal degradation; Wnt signaling stabilizes β-catenin, allowing nuclear translocation and TCF/LEF-mediated transcription. Overexpression of wild-type β-catenin shows modest stabilization; overexpression of activating mutants (S33, S37, T41, S45 phospho-degron mutants) drives strong gain-of-function. For Wnt signaling research, the EDITGENE CTNNB1 Knockout in HEK293 is a workhorse mechanistic platform — HEK293 supports systematic structure-function studies. Rescue with wild-type, exon 3 phospho-degron mutants (S33Y, S37F, T41A, S45F — common in hepatocellular carcinoma, colorectal cancer, endometrial cancer, Wilms tumor, desmoid tumor), or DNA-binding-deficient β-catenin enables comprehensive structure-function and disease modeling. The knockout is valuable for studying Wnt pathway biology, β-catenin-driven cancer mechanisms, and emerging Wnt-targeted therapeutics (porcupine inhibitors LGK974/WNT974, β-catenin/TCF inhibitors PRI-724, BC2059).

Yes. β-catenin rescue experiments are uniquely powerful for Wnt signaling research: • Construct design: use a codon-modified CTNNB1 sequence with a small C-terminal tag (FLAG, HA). β-catenin has N-terminal phospho-degron (S33/S37/T41/S45), central armadillo repeats (TCF/LEF, E-cadherin binding), and C-terminal transactivation domain — preserve all elements. • Constitutively-active rescue: S33Y, S37F, T41A, S45F or Δexon3 mutations bypass GSK3β phosphorylation and destruction complex degradation, generating stable β-catenin — gold-standard for separating Wnt-induced from constitutive β-catenin functions. • Cancer mutation rescue: same exon 3 mutations are common in HCC, CRC, endometrial cancer, Wilms tumor — invaluable for disease modeling. • DNA-binding/TCF-interaction-deficient rescue: armadillo repeat mutations disrupt TCF/LEF binding for separation of transcriptional from junctional functions. • Functional readout: rescue should restore β-catenin-dependent TCF/LEF reporter activity and E-cadherin junctional staining. HEK293 transduces efficiently with lentivirus and supports stable rescue line generation.
