Background
CD79B (also known as B29, Ig beta and B cell
antigen receptor complex-associated protein beta-chain) is a 37-39 kDa member
of the Ig-Superfamily. It is expressed on B cells, and forms a covalent
heterodimer with CD79a. This complex interacts non-covalently with membrane Ig,
forming the B cell antigen receptor. Within this complex, membrane Ig detects
antigen while CD79AB initiates signaling (1). CD79B is also required for
formation of pre-B cells during B cell development. Mature mouse CD79B is a 203 amino acid (aa) type I transmembrane glycoprotein (aa 26-228). It contains an
extracellular region with one V-type Ig-like domain (aa 41-132) and an ITAM‑containing
cytoplasmic domain (aa 184-212) (2). Mouse CD79a and CD79B share only 24% aa
identity. Over aa 29-158, mouse CD79B shares 54% and 78% aa identity with human
and rat CD79B, respectively.
