Automated description from the Alliance of Genome Resources (Release 7.4.0)
Enables GTP-dependent protein binding activity and protein-macromolecule adaptor activity. Involved in several processes, including modulation of chemical synaptic transmission; secretion by cell; and synaptic vesicle clustering. Acts upstream of or within several processes, including chemical synaptic transmission; maintenance of presynaptic active zone structure; and synaptic vesicle maturation. Located in several cellular components, including cytoplasmic vesicle; presynaptic active zone; and terminal bouton. Is active in synaptic vesicle membrane. Is expressed in brain and inner ear. Orthologous to human RAB3A (RAB3A, member RAS oncogene family).
