    SUBCELLULAR LOCALIZATION     plasma membrane
        intracellular
    intracellular,cytoplasm,cytosolic
    text elevation of the intracellular Ca2+ causes a rapid C2 domain-dependent translocation to the plasma membrane, resulting in the activation of the RasGAP activity and the inactivation of the Ras/Mek/Erk pathways
    basic FUNCTION
  • playing a probable role as inhibitory regulator of the ras-cyclic amp pathway
  • Ca(2+)-dependent Ras GTPase-activating protein, switching off the Ras-MAPK pathway following a stimulus that elevates intracellular calcium
  • suppressing RANKL shedding promoted by delta-CAPRI
