Yes. FIG4 rescue experiments require attention to PAS complex scaffolding: • Construct design: use a codon-modified FIG4 sequence with a small C-terminal tag (FLAG, HA). FIG4 has SAC domain phosphatase region and C-terminal VAC14-interaction region — preserve all elements. • Phosphatase-dead rescue: SAC domain catalytic residue mutations abolish phosphatase activity but retain scaffolding function — invaluable for separating catalytic from scaffolding roles. • VAC14-binding-deficient rescue: C-terminal mutations disrupt PAS complex assembly. • CMT4J mutation rescue: patient-derived FIG4 mutations (I41T common in CMT4J, others) enable disease genotype-function studies. • Functional readout: rescue should restore endolysosomal morphology (no enlarged vacuoles) and PI(3,5)P2 levels. 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 CXCR4 (C-X-C chemokine receptor 4, CD184)'s role as the principal CXCL12/SDF-1 receptor or modeling its functions in HIV entry, stem cell mobilization, and WHIM syndrome. The Knockout line is the standard tool for asking whether CXCR4 is required for these processes — CXCR4 is a Gαi-coupled seven-transmembrane GPCR activated by CXCL12/SDF-1α, with established roles in hematopoietic stem cell retention in bone marrow, T-lymphocyte trafficking, and cancer metastasis; CXCR4 is also a co-receptor for X4-tropic HIV entry. Overexpression is useful for studying CXCR4 gain-of-function effects. For HIV, stem cell, and cancer metastasis research, the EDITGENE CXCR4 Knockout in HEK293T is a workhorse mechanistic platform — HEK293T's very high transfection efficiency supports systematic structure-function studies. Rescue with wild-type, signaling-deficient, or WHIM-associated truncation mutant (e.g., R334X — WHIM syndrome causes gain-of-function CXCR4 truncations that resist β-arrestin-mediated internalization) CXCR4 enables comprehensive disease and pharmacology studies. The knockout is a critical specificity tool for ⭐ plerixafor (Mozobil, FDA-approved CXCR4 antagonist for HSC mobilization in lymphoma/myeloma transplants), mavorixafor (Xolremdi, FDA-approved 2024 for WHIM syndrome), motixafortide, and emerging CXCR4-targeted therapies.

Yes. CXCR4 rescue experiments are well-established for chemokine receptor research: • Construct design: use a codon-modified CXCR4 sequence with a small intracellular C-terminal tag (FLAG, HA). CXCR4 is a seven-transmembrane GPCR with extracellular CXCL12-binding pocket — preserve all elements; note that C-terminal tags may affect β-arrestin recruitment. • Surface localization validation: confirm plasma membrane localization before CXCL12 binding studies. • Signaling-deficient rescue: DRY motif mutations disrupt Gαi-coupling. • WHIM mutation rescue: R334X and other C-terminal truncation mutations cause WHIM syndrome by resisting β-arrestin-mediated internalization, generating gain-of-function CXCR4 — invaluable for disease modeling. • HIV co-receptor studies: HIV envelope-mediated entry assays following CXCR4 rescue. • Functional readout: rescue should restore CXCL12-induced Gαi signaling, β-arrestin recruitment, and receptor internalization. HEK293T transduces with very high efficiency and supports stable rescue line generation for systematic CXCR4 mutation analysis.

The choice depends on whether you are studying DLG2 (discs large homolog 2, PSD-93, Chapsyn-110)'s role as a postsynaptic density scaffold or modeling schizophrenia GWAS associations. The Knockout line is the standard tool for asking whether DLG2 is required for these processes — DLG2 is a MAGUK (membrane-associated guanylate kinase) family scaffold protein with PDZ, SH3, and GUK domains, related to PSD-95 (DLG4); DLG2 binds NMDA receptors and other glutamate receptor subunits at excitatory postsynaptic densities, organizing synaptic signaling complexes. Overexpression is useful for studying DLG2 in heterologous expression contexts. Important consideration: DLG2 is principally functional at neuronal synapses — HAP1 is not the physiological context but supports biochemical studies. DLG family member (DLG1/SAP97, DLG3/SAP102, DLG4/PSD-95) expression analysis aids interpretation given functional overlap. DLG2 is one of the strongest schizophrenia GWAS-associated genes and has been characterized in autism spectrum disorder. Rescue with wild-type DLG2 enables structure-function studies. The knockout is valuable for studying MAGUK scaffold biology and emerging psychiatric disease research.

Yes. DLG2 rescue experiments require attention to MAGUK scaffold architecture: • Construct design: use a codon-modified DLG2 sequence with a small C-terminal tag (FLAG, HA). DLG2 has three PDZ domains, SH3 domain, and inactive GUK domain — preserve all elements. • PDZ-mutant rescue: PDZ domain mutations disrupt NMDA receptor (and other PDZ-binding-motif) interactions. • Schizophrenia variant rescue: GWAS-associated DLG2 variants enable disease genotype-function studies. • Functional readout: rescue should restore PDZ-mediated scaffold interactions identified during knockout characterization. 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. EPHA6 is a member of the class A Eph family receptor tyrosine kinases with less-characterized functions compared to other Eph receptors. The Knockout line is appropriate for asking whether EPHA6 is required for predicted activities — EPHA6 is one of the EphA subfamily receptors (EPHA1-10) that bind ephrin-A ligands at cell-cell contact sites, generating bidirectional signaling; EPHA6 has emerging roles in neural development and cancer biology. Overexpression is useful for studying EPHA6 in heterologous expression contexts. For Eph receptor family research, the EDITGENE EPHA6 Knockout in HAP1 provides a clean genetic background for characterizing EPHA6-specific functions. Other EphA family member expression analysis aids interpretation given substantial substrate scope overlap. Rescue with wild-type or kinase-dead EPHA6 is the standard specificity control. The knockout is valuable for studying less-characterized EphA receptor biology and emerging Eph-targeted therapeutics.

Yes. EPHA6 rescue experiments require attention to Eph receptor architecture: • Construct design: use a codon-modified EPHA6 sequence with a small intracellular C-terminal tag (FLAG, HA). EPHA6 has the canonical Eph architecture (LBD, cysteine-rich, fibronectin type III, transmembrane, kinase, SAM, PDZ-binding) — preserve all elements. • Surface localization validation: confirm plasma membrane localization before functional assays. • Kinase-dead rescue: ATP-binding lysine mutation abolishes catalytic activity. • Functional readout: rescue should restore ephrin-A-induced phospho-EPHA6 signaling. 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 ELFN1's role as a trans-synaptic organizer and mGluR7 partner or modeling its functions in synaptic specificity. The Knockout line is the standard tool for asking whether ELFN1 is required for these processes — ELFN1 is a postsynaptic transmembrane LRR-Fn protein that, via its extracellular LRR, binds the presynaptic mGluR7 (metabotropic glutamate receptor 7), recruiting it to specific synapses (e.g., OLM interneurons in hippocampus) to confer synapse-specific tonic glutamate sensing. Overexpression is useful for studying ELFN1 in heterologous expression contexts. Important consideration: ELFN1 is principally functional at neuronal synapses — HAP1 is not the physiological context for synaptic ELFN1 function but supports biochemical studies. ELFN2 paralog expression analysis aids interpretation. This product complements the parallel ELFN2 Knockout in HAP1 (also available) for paralog-specific functional dissection. The knockout is valuable for studying ELFN-mGluR trans-synaptic interactions in heterologous expression contexts; physiological synapse studies require neuronal models.

Yes. ELFN1 rescue experiments require attention to mGluR7-binding architecture: • Construct design: use a codon-modified ELFN1 sequence with a small intracellular C-terminal tag (FLAG, HA). ELFN1 has the canonical LRR-Fn architecture — preserve all elements. • Surface localization validation: confirm plasma membrane localization before mGluR7 interaction studies. • mGluR7-binding-deficient rescue: LRR domain mutations disrupt mGluR7 binding and serve as the standard specificity control. • Functional readout: rescue should restore ELFN1-mGluR7 trans-cellular interaction. 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 GRK5's role as a GPCR kinase or its functions in cardiac biology and Alzheimer's disease pathology. The Knockout line is the standard tool for asking whether GRK5 is required for these processes — GRK5 is closely related to GRK6 and phosphorylates activated GPCRs (β-adrenergic receptors in cardiomyocytes, others); GRK5 has emerged as a target in heart failure and is implicated in Alzheimer's disease pathology. Overexpression is useful for studying GRK5 gain-of-function effects. Important consideration: GRK family paralog expression analysis aids interpretation. This product complements the parallel GRK6 Knockout in HAP1 (also available) for paralog-specific functional dissection. Rescue with wild-type or kinase-dead GRK5 is the standard specificity control. The knockout is valuable for studying cardiac GRK5 biology (in heterologous cardiac contexts) and emerging GRK5-targeted heart failure therapeutics.

Yes. GRK5 rescue experiments require attention to membrane anchoring: • Construct design: use a codon-modified GRK5 sequence with a small C-terminal tag (FLAG, HA). GRK5 has the canonical GRK4-subfamily architecture with C-terminal palmitoylation/membrane anchor — preserve all elements. • Kinase-dead rescue: ATP-binding lysine mutation abolishes catalytic activity. • Functional readout: rescue should restore GRK5-substrate GPCR phosphorylation. 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 HDAC7's role as a class IIa histone deacetylase or its functions in T cell biology and vascular development. The Knockout line is the standard tool for asking whether HDAC7 is required for these processes — HDAC7 is a class IIa HDAC (with HDAC4, HDAC5, HDAC9) that shuttles between nucleus and cytoplasm based on phosphorylation status; class IIa HDACs have very low intrinsic deacetylase activity and primarily function as MEF2 transcription factor co-repressors and recruiters of HDAC3-containing complexes. Overexpression is useful for studying HDAC7 gain-of-function effects. Important consideration: class IIa HDACs (HDAC4, 5, 7, 9) share substantial substrate scope as MEF2 co-repressors — single HDAC7 knockout may show modest phenotypes if other class IIa HDACs compensate. This product complements the parallel HDAC4 Knockout in HAP1 (also available) for class IIa HDAC family functional dissection. Rescue with wild-type or 14-3-3-binding-resistant (phospho-site mutations) HDAC7 enables structure-function studies. The knockout is a critical specificity control for class IIa-selective HDAC inhibitors (TMP269, MC1568) in development.

Yes. HDAC7 rescue experiments require attention to nuclear-cytoplasmic shuttling architecture: • Construct design: use a codon-modified HDAC7 sequence with a small C-terminal tag (FLAG, HA). HDAC7 has N-terminal regulatory region with 14-3-3-binding phospho-sites (S155, S181, S321), central HDAC catalytic domain, and C-terminal NLS — preserve all elements. • 14-3-3-binding-resistant rescue: S155A/S181A/S321A triple phospho-site mutations abolish 14-3-3-mediated cytoplasmic retention, generating constitutively nuclear HDAC7. • Catalytically-dead rescue: HDAC catalytic domain mutations abolish any intrinsic deacetylase activity (class IIa HDACs have very low intrinsic activity, primarily acting as scaffolds). • Functional readout: rescue should restore MEF2 corepression and target gene attenuation. 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. ELFN2 (extracellular leucine-rich repeat fibronectin domain 2) is a transmembrane protein with characterized roles in synaptic organization and emerging functions in mGluR partnership. The Knockout line is appropriate for asking whether ELFN2 is required for predicted activities — ELFN1 and ELFN2 are postsynaptic transmembrane proteins with extracellular LRR and fibronectin domains; ELFN2 has been characterized as a trans-synaptic organizer with implications for synaptic specificity. Overexpression is useful for studying ELFN2 in heterologous expression contexts. For synaptic biology research, the EDITGENE ELFN2 Knockout in HAP1 provides a clean genetic background for structure-function studies — HAP1 is not the physiological context for synaptic ELFN2 function but supports biochemical studies. ELFN1 paralog expression analysis aids interpretation. This product complements the parallel ELFN1 Knockout in HAP1 (also available) for paralog-specific functional dissection. Rescue with wild-type ELFN2 is the standard specificity control. The knockout is valuable for studying ELFN family biochemistry and emerging trans-synaptic organization research.

Yes. ELFN2 rescue experiments require attention to extracellular LRR-Fn architecture: • Construct design: use a codon-modified ELFN2 sequence with a small intracellular C-terminal tag (FLAG, HA).
