Background: Neurexin 1 beta/NXRN1b

Neurexin 1 beta is an 80 kDa member of the Neurexin family of proteins. It is expressed on neuronal presynaptic membranes and contributes to synapse formation through binding to postsynaptic neuroligins. An alternate start site in the Neurexin 1 gene generate an alpha - (long) and beta - (short) isoform. Mature rat Neurexin 1 beta is a type I transmembrane glycoprotein that is 468 amino acids (aa) in length. It has a 346 aa extracellular region (aa 47‑392) that contains one laminin-like G domain (aa 91‑264). Within the G domain, the presence or absence of a splice site (aa 201‑230) materially impacts neuroligin binding. Over aa 47‑392, rat Neurexin 1 beta is 100% and 98% aa identical to mouse and human Neurexin 1 beta, respectively.
