ACAP3 Knockout Cell Line (Hela)

The choice depends on the experimental question. ACAP3 (ArfGAP with coiled-coil, ANK repeat and PH domain containing 3) is an Arf6 GTPase-activating protein with characterized roles in neuronal biology. The Knockout line is appropriate for asking whether ACAP3 is required for predicted activities — ACAP3 is an Arf6-specific GAP (GTPase-activating protein) with PH, ArfGAP, and ankyrin repeat domains; ACAP3 has been characterized in neuronal migration and neurite outgrowth through Arf6 regulation. Overexpression is useful for studying ACAP3 in heterologous expression contexts. For Arf6 signaling research, the EDITGENE ACAP3 Knockout in HeLa provides a clean genetic background for characterizing ACAP3-specific functions. Other ACAP family members (ACAP1, ACAP2) expression analysis aids interpretation. Rescue with wild-type or GAP-dead ACAP3 enables structure-function studies. The knockout is valuable for studying Arf6 GTPase regulation, membrane trafficking, and emerging ACAP3 functions in neuronal biology.

Primary applications: • Arf6 GAP activity: Arf6-GTP hydrolysis analysis in ACAP3-null cells. • Membrane trafficking: Arf6-dependent endocytic recycling and membrane trafficking analysis. • Neuronal biology: in heterologous neural-relevant contexts, ACAP3's role in neurite outgrowth. • ACAP family dissection: ACAP1, ACAP2 expression analysis to interpret ACAP3-specific functions. EDITGENE recommends this model for researchers investigating Arf6 GTPase regulation and membrane trafficking.

Yes. ACAP3 rescue experiments require attention to multi-domain architecture: • Construct design: use a codon-modified ACAP3 sequence with a small C-terminal tag (FLAG, HA). ACAP3 has BAR, PH, ArfGAP, and ankyrin repeat domains — preserve all elements. • GAP-dead rescue: ArfGAP domain arginine finger mutations abolish Arf6-GAP activity. • Functional readout: rescue should restore Arf6-GTP hydrolysis and membrane trafficking. HeLa transduces efficiently with lentivirus and supports stable rescue line generation.
