| Target description: | Protein bassoon (UniProt: Q9UPA5; also known as Zinc finger protein 231, BSN) is encoded by the BSN (also known as KIAA0434, ZNF231) gene (Gene ID: 8927) in human. BSN is a multi-domain peripheral membrane protein that is exclusively expressed in brain. It serves as a scaffold protein of the presynaptic cytomatrix at the active zone, the region in the synapse where neurotransmitter is released. At the presynaptic active zone, it regulates the spatial organization of synaptic vesicle cluster, the protein complexes that execute membrane fusion and compensatory endocytosis. It promotes vesicular replenishment and, consequently, a large standing pool of readily releasable synaptic vesicles at the endbulb synapse. BSN are transported on Golgi-derived membranous organelles, called Piccolo-Bassoon transport vesicles (PTVs), from the neuronal soma to distal axonal locations, where they participate in assembling new synapses. It is known to mediate synapse to nucleus communication leading to reconfiguration of gene expression by associating with the transcriptional corepressor CTBP1 and by subsequently reducing the size of its pool available for nuclear import. Mutant mice deficient in functional Bassoon are reported to suffer from epileptic seizures and have dysfunctional hippocampal synapses. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
