General annotation (Comments)

Function	GTPase-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. Ref.3 Ref.10 Ref.11 Ref.12
Enzyme regulation	GAP activity is stimulated by phosphatidylinositol 4,5-bisphosphate (PIP2) and, to a lesser extent, by phosphatidylinositol 3,4,5-trisphosphate (PIP3). Phosphatidic acid potentiates PIP2 stimulation.
Subunit structure	Isoform 1 interacts with EPB41L1, PLCG1, NF2, HOMER1 and HOMER2 By similarity. Isoform 2 interacts with activated AKT1 in the presence of guanine nucleotides, and with the AP-1 complex. Ref.10 Ref.11 Ref.12
Subcellular location	Isoform 1: Cytoplasm Ref.3 Ref.10 Ref.18. Nucleus Ref.3 Ref.10 Ref.18. Isoform 2: Cytoplasm Ref.3 Ref.10 Ref.18.
Tissue specificity	Isoform 1 is brain-specific. Isoform 2 is ubiquitously expressed, with highest levels in brain and heart. Ref.3 Ref.10 Ref.11 Ref.12 Ref.13
Domain	G 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 modification	Isoform PIKE-A is phosphorylated at Tyr-682 and Tyr-774 by FYN, preventing its apoptotic cleavage. Ref.14
Sequence similarities	Belongs to the centaurin gamma-like family. Contains 2 ANK repeats. Contains 1 Arf-GAP domain. Contains 1 PH domain.
Sequence caution	The sequence BAA11484.2 differs from that shown. Reason: Erroneous initiation.
