Summary: 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, Dec 2024]
Expression: Broad expression in cortex adult (RPKM 15.2), frontal lobe adult (RPKM 14.2) and 16 other tissues See more

Piccolo puncta sandwiched Bassoon puncta and aligned in a Piccolo-Bassoon-Piccolo structure in adult neuromuscular junctions (NMJs). P/Q-type voltage-gated calcium channel (VGCC) puncta colocalized with Bassoon puncta. The P/Q-type VGCC and Bassoon protein levels decreased significantly in NMJs from aged mouse. In contrast, the Piccolo levels in NMJs from aged mice were comparable to levels in adult mice.

Authors conclude that bassoon promotes vesicular replenishment and, consequently, a large standing pool of readily releasable synaptic vesicles at the endbulb synapse.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
