Extra Details:
VPREB1 belongs to the immunoglobulin superfamily and is expressed selectively at the early stages of B cell development; namely; in proB and early preB cells. This gene encodes the iota polypeptide chain that is associated with the Ig-mu chain to form a molecular complex which is expressed on the surface of pre-B cells. The complex is thought to regulate Ig gene rearrangements in the early steps of B-cell differentiation.CD179a (VpreB) is a 126 aa-long polypeptide with apparent MW of 16-18 kDa. It is expressed selectively at the early stages of B cell development; namely; in proB and early preB cells. CD179a has an Ig V domain-like structure; but lacks the last beta-strand (beta7) of a typical V domain. Instead; it has a carboxyl terminal end that shows no sequence homologies to any other proteins. CD179a associates non-covalently with CD179b (lambda5 or lambda-like) carrying an Ig C domain-like structure to form an Ig light chain-like structure; which is called the surrogate light chain or pseudo light chain. In this complex; the incomplete V domain of CD179a appears to be complemented by the extra beta7 strand of CD179b. On the surface of early preB cells; CD179a/CD179b surrogate light chain is disulfide-linked to membrane-bound Ig mu heavy chain in association with a signal transducer CD79a/CD79b heterodimer to form a B cell receptor-like structure; so-called preB cell receptor (preBCR). Though no CD179a-related human disease or pathology has been reported yet; the deficiency of other components of preB cell receptor such as CD179b; Ig mu heavy chain and CD79a has been shown to result in severe impairment of B cell development and agammaglobulinemia in human. PreBCR transduces signals for: 1) cellular proliferation; differentiation from the proB cell to preB cell stage; 2) allelic exclusion at the Ig heavy chain gene locus; and 3) promotion of Ig light chain gene rearrangements. Thus; preBCR functions as a checkpoint in early B cell development to monitor the production of Ig mu heavy chain through a functional rearrangement of Ig heavy chain gene as well as the potency of Ig mu heavy chain to associate with Ig light chain.
