Yes. SGK3 rescue experiments require attention to PI(3)P-dependent activation: • Construct design: use a codon-modified SGK3 sequence with a small C-terminal tag (FLAG, HA). SGK3 contains an N-terminal PX domain (PI(3)P-binding) and kinase domain — preserve both. • Kinase-dead rescue: the K191A mutation in the ATP-binding lysine abolishes catalytic activity and is the standard specificity control. • PX-domain-mutant rescue: PI(3)P-binding-deficient mutations (e.g., R90A) disrupt endosomal targeting without affecting kinase activity, enabling activation mechanism studies. • Functional readout: rescue should restore SGK3 substrate phosphorylation (NDRG1) and PI3K pathway redundancy under AKT inhibition. 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 SIK2 (salt-inducible kinase 2)'s role as an AMPK-related kinase regulating CRTC transcriptional coactivators or its emerging functions in metabolism and cancer biology. The Knockout line is the standard tool for asking whether SIK2 is required for phosphorylating CRTC2, CRTC3, and HDAC4/5 — SIK2 functions as a metabolic regulator with established roles in glucose and lipid homeostasis. Overexpression is useful for studying SIK2 gain-of-function in metabolic contexts or cancer biology. Important consideration: SIK1, SIK2, and SIK3 share substantial functional overlap with overlapping substrate scopes. Single SIK2 knockout in HAP1 may show modest phenotypes if its paralogs compensate. Rescue with wild-type or kinase-dead SIK2 is the standard specificity control. The knockout serves as a critical genetic tool for SIK2 inhibitors (HG-9-91-01, YKL-05-099) in development for metabolic disease and cancer.

Yes. SIK2 rescue experiments require attention to AMPK-family activation: • Construct design: use a codon-modified SIK2 sequence with a small C-terminal tag (FLAG, HA). SIK2 contains an N-terminal kinase domain and C-terminal regulatory regions including ubiquitin-associated (UBA) domain — preserve all elements. • Kinase-dead rescue: the K49M mutation in the ATP-binding lysine abolishes catalytic activity and is the standard specificity control. • T-loop phosphorylation: LKB1-dependent T175 phosphorylation is required for SIK2 activation — rescue interpretation should consider LKB1 status. • Functional readout: rescue should restore CRTC2/CRTC3 phosphorylation and downstream CREB target gene regulation. 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 SLC13A5 (INDY, Citrate Transporter)'s role in hepatic citrate uptake or modeling early infantile epileptic encephalopathy 25. The Knockout line is the standard tool for asking whether SLC13A5 is required for cellular citrate uptake — SLC13A5 is the principal hepatic plasma membrane citrate importer, mediating sodium-coupled citrate uptake for cytoplasmic acetyl-CoA generation and de novo lipogenesis. Overexpression is useful for studying SLC13A5 as a metabolic disease target. For metabolic disease research, the EDITGENE SLC13A5 Knockout in Huh-7 is highly relevant — Huh-7 has hepatocellular origin matching SLC13A5's physiological context. SLC13A5 mutations cause EIEE25 (autosomal recessive early infantile epileptic encephalopathy with elevated CSF citrate) — disease variant rescue enables genotype-function studies. SLC13A5 is also a metabolic disease therapeutic target (mINDY): inhibition is investigated for fatty liver disease and type 2 diabetes. Rescue with wild-type or transport-deficient SLC13A5 is the standard specificity control.

Yes. SLC13A5 rescue experiments are well-established for hepatic citrate biology: • Construct design: use a codon-modified SLC13A5 sequence with a small C-terminal tag (FLAG, HA). The 11-transmembrane SLC13 architecture must be preserved. • EIEE25 mutation rescue: patient-derived SLC13A5 mutations enable disease genotype-function correlation studies. • Transport-deficient rescue: substrate-binding pocket mutations enable structure-function studies and inhibitor specificity research. • Functional readout: rescue should restore sodium-dependent citrate uptake and downstream lipogenesis from citrate-derived acetyl-CoA. Huh-7 transduces efficiently with lentivirus and supports stable rescue line generation in a hepatocyte-relevant context.

The choice depends on whether you are studying SLC15A1 (PEPT1)'s role as the principal intestinal di/tripeptide transporter or its functions in oral drug bioavailability. The Knockout line is the standard tool for asking whether PEPT1 is required for cellular uptake of dipeptides, tripeptides, and peptide-mimetic drugs — PEPT1 is the principal apical peptide transporter in intestinal epithelium. Overexpression is useful for testing peptide-substrate transport or for studying PEPT1-targeted prodrugs (valacyclovir, valganciclovir). For oral drug bioavailability research, the EDITGENE PEPT1 Knockout in Huh-7 enables study of peptide transporter pharmacology — though Huh-7 has hepatic rather than intestinal origin. PEPT2 (SLC15A2) paralog expression analysis aids interpretation. Rescue with wild-type or transport-deficient PEPT1 is the standard specificity control for PEPT1-targeted prodrug research. The knockout is valuable for PEPT1-targeted drug delivery strategy development.

Yes. PEPT1 rescue experiments are well-established for peptide transport research: • Construct design: use a codon-modified SLC15A1 sequence with a small C-terminal tag (FLAG, HA). PEPT1 has 12 transmembrane domains with apical sorting determinants. • Surface localization validation: confirm plasma membrane localization before transport assays. • Transport-deficient rescue: substrate-binding pocket mutations enable structure-function studies. • Functional readout: rescue should restore dipeptide uptake activity and pH-dependent peptide-mimetic prodrug uptake. Huh-7 transduces efficiently with lentivirus and supports stable rescue line generation.

The choice depends on whether you are studying SLC22A15 (FLIPT1, fly-like putative transporter 1)'s role as an SLC22 family member or its emerging functions in cation/anion transport. The Knockout line is appropriate for asking whether SLC22A15 is required for predicted transport activities, though its substrate specificity is less well characterized than canonical OCT/OAT family members. Overexpression is useful for substrate identification through transport activity screening. For SLC22 family research, the EDITGENE SLC22A15 Knockout in Huh-7 enables characterization of this transporter's substrate scope and tissue-relevant functions. Untargeted metabolomic profiling in the knockout can identify candidate substrate classes. Rescue with wild-type SLC22A15 enables initial functional characterization.

Yes, and rescue experiments are essential for an under-characterized factor: • Construct design: use a codon-modified SLC22A15 sequence with a small C-terminal tag (FLAG, HA). The predicted SLC22 family architecture should be preserved. • Discovery-oriented rescue: parallel rescue with wild-type construct during phenotypic characterization distinguishes true gene-dependent phenotypes from off-target effects. • Localization validation: confirm subcellular localization given limited prior data on SLC22A15. • Functional readout: rescue should restore phenotypes identified during discovery characterization; substrate-specific transport assays test predicted activities. Huh-7 transduces efficiently with lentivirus and supports stable rescue line generation.

The choice depends on whether you are studying SLC23A1 (SVCT1)'s role as a sodium-dependent vitamin C (ascorbate) transporter or its contributions to systemic vitamin C homeostasis. The Knockout line is the standard tool for asking whether SVCT1 is required for ascorbate uptake — SVCT1 is the principal apical vitamin C transporter in intestinal epithelium and kidney proximal tubule. Overexpression is useful for testing transport activity or for studying SVCT1 polymorphisms associated with vitamin C status. For vitamin C biology research, the EDITGENE SVCT1 Knockout in Huh-7 enables study of hepatic ascorbate uptake — though SVCT1's principal physiological sites are intestinal and renal apical membranes. SLC23A2 (SVCT2) paralog expression analysis is important; SVCT2 is the high-affinity transporter expressed in most other tissues. Rescue with wild-type or transport-deficient SVCT1 enables structure-function studies. Common SLC23A1 polymorphisms (e.g., V264M, V165L) affect circulating vitamin C levels.

Yes. SVCT1 rescue experiments require attention to sodium coupling and apical targeting: • Construct design: use a codon-modified SLC23A1 sequence with a small C-terminal tag (FLAG, HA). SVCT1 has 12 transmembrane domains — N-terminal tags must not disrupt topology. • Surface localization validation: confirm plasma membrane localization by cell surface biotinylation; apical sorting requires specific signals. • Polymorphism rescue: clinically relevant SLC23A1 polymorphisms (V264M, V165L) affecting circulating vitamin C levels enable pharmacogenomic studies. • Functional readout: rescue should restore sodium-dependent ascorbate uptake measured by ¹⁴C-ascorbate uptake or LC-MS detection. Huh-7 transduces efficiently with lentivirus and supports stable rescue line generation.

The choice depends on whether you are studying RXRB's role as a heterodimerization partner for multiple nuclear receptors or its specific contributions distinct from RXRA and RXRG. The Knockout line is appropriate for asking whether RXRB is required for nuclear receptor signaling — RXRs are obligate heterodimer partners for RAR, PPAR, LXR, FXR, VDR, TR, and other 'non-permissive' or 'permissive' partner receptors. Overexpression is useful for studying RXRB-specific functions in heterodimer formation. Important consideration: RXRA, RXRB, and RXRG have substantial functional overlap as heterodimer partners. Single RXRB knockout in HAP1 may show modest phenotypes if RXRA and RXRG compensate. The EDITGENE Knockout in HAP1 is most informative when combined with assessment of remaining RXR paralog expression. Rescue with wild-type or DNA-binding-deficient/ligand-binding-deficient RXRB enables structure-function studies. This product complements the parallel RXRA&RXRB Double Knockout in A-549 (also available) for comprehensive RXR family dissection.

Yes. RXRB rescue experiments require attention to multi-domain nuclear receptor architecture: • Construct design: use a codon-modified RXRB sequence with a small C-terminal tag (FLAG, HA). RXRB has the canonical nuclear receptor architecture (N-terminal A/B domain, DNA-binding C domain, hinge, ligand-binding E domain) — preserve all elements. • DNA-binding-deficient rescue: zinc finger DBD mutations (e.g., C-to-S substitutions) abolish DNA binding and serve as specificity controls for transcription-dependent functions. • Ligand-binding-deficient rescue: LBD mutations affecting 9-cis-retinoic acid binding (e.g., F315W or similar) enable distinguishing ligand-dependent from constitutive activities. • Functional readout: rescue should restore heterodimer-mediated transcription on DR-element reporters and partner receptor-specific target gene expression. 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 SHPRH's role as a ubiquitin ligase mediating PCNA polyubiquitination during DNA damage tolerance or its functions in genome stability maintenance. The Knockout line is the standard tool for asking whether SHPRH is required for K63-linked polyubiquitination of PCNA at lysine 164 — SHPRH and HLTF redundantly catalyze this modification, which switches translesion synthesis from error-prone to template-switching error-free pathway. Overexpression is useful for testing SHPRH activity or for studying its tumor suppressor functions. For DNA damage tolerance research, the EDITGENE SHPRH Knockout in HAP1 is a clean genetic background for studying PCNA-K164 polyubiquitination biology. HLTF expression analysis is essential given functional redundancy — combined SHPRH/HLTF analyses provide comprehensive characterization of K63-polyubiquitin-dependent template switching. Rescue with wild-type or RING-domain-mutant (E3-ligase-dead) SHPRH enables structure-function studies.

Yes. SHPRH rescue experiments require attention to multi-domain architecture: • Construct design: SHPRH is large (~1683 amino acids); use codon-modified sequences with C-terminal tags (FLAG, HA). The N-terminal H15 (linker histone H1.5) domain, central SF2 helicase domain, RING domain (E3 ligase), and C-terminal regions should all be preserved. • RING-dead rescue: RING domain mutations abolish E3 ligase activity and are the standard specificity control for K63-polyubiquitin ligase function. • Helicase-dead rescue: ATP-binding mutations in the SF2 domain enable separation of ATPase from E3 ligase functions. • Functional readout: rescue should restore K63-polyubiquitinated PCNA following DNA damage and template switching activity. 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.
