CD79b (CD79b Antigen, CD79b Molecule Immunoglobulin-associated beta, CD79b Protein, B-cell Antigen Receptor Complex-associated Protein beta Chain, B-cell-specific Glycoprotein B29, B29, Ig-beta, IGB, Immunoglobulin-associated B29 Protein)

CD79B is a 36-40kD member of the Ig-Superfamily. It is expressed on B cells, and forms a covalent heterodimer with 44-49kD CD79A. This complex interacts noncovalently with membrane Ig, forming the B cell antigen receptor. Within this complex, membrane Ig detects antigen while CD79A:B initiates signaling. Mature human CD79B is a 201aa type I tranamembrane glycoprotein (aa29-229). It contains an extracellular region with one V-type Ig-like domain (aa38-138) and an ITAM-containing cytoplasmic domain (aa181-229). There is an alternative splice form that shows a deletion of aa41-144 and appears after B cell activation. Human CD79A and B share only 26aa identity. Over aa29-159, human CD79B shares 54aa identity with mouse CD79B.\n\nApplications:\nSuitable for use in Flow Cytometry and Western Blot.
