Bsn Gene Summary [Mouse]
A structural constituent of presynaptic active zone. Involved in protein localization to synapse; regulation of synaptic vesicle cycle; and synaptic vesicle clustering. Located in several cellular components, including cell surface; postsynaptic density; and presynaptic active zone. Is active in several cellular components, including GABA-ergic synapse; Schaffer collateral - CA1 synapse; and cochlear hair cell ribbon synapse. Is expressed in nervous system and retina. Used to study epilepsy. Orthologous to human BSN (bassoon presynaptic cytomatrix protein). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Bsn often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
