Function

edit

Members of the RAB3 protein family (see RAB3A; MIM 179490) are implicated in regulated exocytosis of neurotransmitters and hormones. RAB3GAP, which is involved in regulation of RAB3 activity, is a heterodimeric complex consisting a 130-kD catalytic subunit and a 150-kD noncatalytic subunit (MIM 609275). RAB3GAP specifically converts active RAB3-GTP to the inactive form RAB3-GDP (Aligianis et al., 2005).[supplied by OMIM][7] RAB3GAP is reported to modulate basal and rapamycin-induced autophagy in human fibroblasts and C. elegans.[8] Further, the RAB3GAP1 knockdown has shown to affect the autophagy and mineralization potential of human primary osteoblasts.[9]
