Entrez Gene Summary for CD79B Gene

  • The B lymphocyte antigen receptor is a multimeric complex that includes the antigen-specific component, surface immunoglobulin (Ig). Surface Ig non-covalently associates with two other proteins, Ig-alpha and Ig-beta, which are necessary for expression and function of the B-cell antigen receptor. This gene encodes the Ig-beta protein of the B-cell antigen component. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Jul 2008]

GeneCards Summary for CD79B Gene

CD79B (CD79b Molecule, Immunoglobulin-Associated Beta) is a Protein Coding gene. Diseases associated with CD79B include agammaglobulinemia 6 and autosomal agammaglobulinemia. Among its related pathways are Downstream Signaling Events Of B Cell Receptor (BCR) and Class I MHC mediated antigen processing and presentation. GO annotations related to this gene include transmembrane signaling receptor activity.

UniProtKB/Swiss-Prot for CD79B Gene

  • Required in cooperation with CD79A for initiation of the signal transduction cascade activated by the B-cell antigen receptor complex (BCR) which leads to internalization of the complex, trafficking to late endosomes and antigen presentation. Enhances phosphorylation of CD79A, possibly by recruiting kinases which phosphorylate CD79A or by recruiting proteins which bind to CD79A and protect it from dephosphorylation.
