Target

  • 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.
  • Tissue specificity
    Isoform 1 is brain-specific. Isoform 2 is ubiquitously expressed, with highest levels in brain and heart.
  • Sequence similarities
    Belongs to the centaurin gamma-like family.
    Contains 2 ANK repeats.
    Contains 1 Arf-GAP domain.
    Contains 1 PH domain.
  • 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
    modifications
    Isoform PIKE-A is phosphorylated at Tyr-682 and Tyr-774 by FYN, preventing its apoptotic cleavage.
  • Cellular localization
    Cytoplasm and Cytoplasm. Nucleus.

Answer

Thank you for your interest.

I have conducted a search for you and found 7 antibodies against this target (PIKE, GGAP2 AGAP2, Centaurin). Here are some which have been tested in Western blot application and Immunostaining, it seems that none of them have been characterized specifically for IP yet:

ab21271: IHC-P, WB

ab105332: IHC-P, WB

ab110956: ICC, WB

ab111987: IHC-P, WB

If you need any further assistance in the future, please do not hesitate to contact me.
