  • FunctionGTPase-activating protein (GAP) for ARF1 and ARF5, which also shows strong GTPase activity. Isoform 1 participates in the prevention of neuronal apoptosis by enhancing PI3 kinase activity. It aids the coupling of metabotropic glutamate receptor 1 (GRM1) to cytoplasmic PI3 kinase by interacting with Homer scaffolding proteins, and also seems to mediate anti-apoptotic effects of NGF by activating nuclear PI3 kinase. Isoform 2 does not stimulate PI3 kinase but may protect cells from apoptosis by stimulating Akt. It also regulates the adapter protein 1 (AP-1)-dependent trafficking of proteins in the endosomal system. It seems to be oncogenic. It is overexpressed in cancer cells, prevents apoptosis and promotes cancer cell invasion.
  • Tissue specificityIsoform 1 is brain-specific. Isoform 2 is ubiquitously expressed, with highest levels in brain and heart.
  • Sequence similaritiesBelongs to the centaurin gamma-like family.
    Contains 2 ANK repeats.
    Contains 1 Arf-GAP domain.
    Contains 1 PH domain.
  • DomainG domain binds GTP and has GTPase activity.
    Arf-GAP domain interacts with G domain and may regulate its GTPase activity.
    Although both PH domains of isoforms 1 and 2 bind phospholipids, they differently regulate subcellular location. PH domain of isoform 1 directs the protein to the nucleus, but PH domain of isoform 2 directs it to the cytosol. PH domain of isoform 2 is required for binding to AP-1.
  • Post-translational
    Isoform PIKE-A is phosphorylated at Tyr-682 and Tyr-774 by FYN, preventing its apoptotic cleavage.
  • Cellular localizationCytoplasm and Cytoplasm. Nucleus.
  • Information by UniProt
