Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables transmembrane transporter binding activity. A structural constituent of presynaptic active zone. Involved in several processes, including neurotransmitter secretion; regulation of calcium-dependent activation of synaptic vesicle fusion; and regulation of nervous system process. Acts upstream of or within calcium ion-regulated exocytosis of neurotransmitter; regulation of long-term neuronal synaptic plasticity; and regulation of membrane potential. Located in several cellular components, including inhibitory synapse; postsynaptic density; and presynaptic active zone cytoplasmic component. Is active in GABA-ergic synapse and glutamatergic synapse. Is extrinsic component of presynaptic active zone membrane. Is expressed in brain and cerebellum. Orthologous to human RIMS1 (regulating synaptic membrane exocytosis 1).
