Background: Semaphorin 4B

Semaphorin 4B (Sema4B; also SemaC) is a 95‑100 kDa, class IV member of the Semaphorin family of proteins. It is expressed in neurons, and following PSD-95 induced clustering, participates in the formation or functioning of glutamatergic synapses. Mature human Sema4B is a type I transmembrane glycoprotein that is 794 amino acids (aa) in length. It contains a 674 aa extracellular region (aa 39‑832) that is characterized by one Sema domain (aa 65‑502), a PSI region (aa 520‑574), and an Ig-like C2-type domain (aa 599‑658). There is one potential soluble splice variant that shows a 29 aa substitution for aa 707‑832. Over aa 39‑712, human Sema4B shares 86% aa identity with mouse Sema4B.
