Rab3a - RAB3A, member RAS oncogene family

Enables several functions, including ATPase binding activity; GTP binding activity; and protein C-terminus binding activity. Involved in regulation of secretion by cell; regulation of synaptic vesicle priming; and synaptic vesicle cycle. Located in several cellular components, including cytosol; secretory vesicle; and terminal bouton. Part of protein-containing complex. Is anchored component of synaptic vesicle membrane. Orthologous to human RAB3A (RAB3A, member RAS oncogene family). [provided by Alliance of Genome Resources, Apr 2022]
