Gene: RAB3B (RAB3B, member RAS oncogene family) Homo sapiens
Symbol: RAB3B
Name: RAB3B, member RAS oncogene family
Description: Exhibits GDP binding activity; GTPase activity; and myosin V binding activity. Involved in several processes, including positive regulation of dopamine uptake involved in synaptic transmission; regulation of synaptic vesicle cycle; and regulation of vesicle size. Localizes to anchored component of synaptic vesicle membrane; dopaminergic synapse; and perinuclear region of cytoplasm; INTERACTS WITH 17beta-estradiol; 17beta-hydroxy-5alpha-androstan-3-one; 2-hydroxypropanoic acid.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: brain antigen RAB3B; ras-related protein Rab-3B
