EPHA6 Knockout HAP1 Cell Line

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.

Primary applications: • Ephrin-A binding: ephrin-A1, ephrin-A5 binding analysis in EPHA6-null cells. • EphA family comparative studies: parallel analysis with EPHA2 Knockout in HEK293 (also available) for EphA subfamily characterization. • Discovery proteomics: interactome analysis in EPHA6-null versus rescued cells. • Kinase activity: phospho-EPHA6 and substrate phosphorylation analysis. EDITGENE recommends this model for researchers investigating less-characterized EphA receptor biology.

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.
