[[http://www.uniprot.org/uniprot/CD79B_HUMAN CD79B_HUMAN]] Autosomal agammaglobulinemia. Defects in CD79B are the cause of agammaglobulinemia type 6 (AGM6) [MIM:[http://omim.org/entry/612692 612692]]. It is a primary immunodeficiency characterized by profoundly low or absent serum antibodies and low or absent circulating B-cells due to an early block of B-cell development. Affected individuals develop severe infections in the first years of life.<ref>PMID:17675462</ref> | |||
==Function== | |||
[[http://www.uniprot.org/uniprot/CD79B_HUMAN CD79B_HUMAN]] 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.<ref>PMID:8617796</ref> <ref>PMID:9057631</ref> <ref>PMID:12097390</ref> | |||
