basic FUNCTION
  • involved in exocytosis and particularly in neurotransmitter release
  • stimulating the GTPase activity of RAB3A and regulating synaptic transmission and plasticity by limiting the amount of the GTP-bound form of RAB3A
  • with RAB3GAP2 encode the catalytic and noncatalytic subunits of the hetrodimeric enzyme RAB3GAP (RAB3GTPase-activating protein), a key regulator of the RAB3 cycle
  • binding of VAPB to RAB3GAP1 is implicated in the regulation of nuclear envelope formation through ERGIC
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS exocytosis transport
    PATHWAY
    metabolism
    signaling
    a component two subunits: the catalytic subunit p130 and the noncatalytic subunit p150
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • VAPB directly binds to RAB3 GTPase activating protein 1 (RAB3GAP1), the catalytic subunit of RAB3GAP, through the two phenylalanines (FF) in an acidic tract (FFAT)-like motif of RAB3GAP1
  • FOXC1 regulates the expression of RAB3GAP1, RAB3GAP2 and SNAP25, three genes with central roles in both exocytosis and endocytosis, responsible for extracellular trafficking
