UniprotKB/SwissProt ID: BSN_RAT (O88778)
Gene Name: Bsn
Organism: Rattus norvegicus (Rat).
Function: Is thought to be involved in the organization of the cytomatrix at the nerve terminals active zone (CAZ) which regulates neurotransmitter release. Seems to act through binding to ERC2/CAST1. Essential in regulated neurotransmitter release from a subset of brain glutamatergic synapses. Involved in the formation of the retinal photoreceptor ribbon synapses (By similarity).
Other Modifications: View all modification sites in dbPTM
Protein Subcellular Localization: Cytoplasm. Cell junction, synapse, synaptosome. Cytoplasm, cytoskeleton. Note=Localized to the active zone of presynaptic density. In retina, is localized in the outer plexiform layer at ribbon synapses formed by rods and cones but was absent from basal
