Description
The B-cell Antigen receptor constitutes a disulphide linked heterodimer, consisting of CD79a (mb1) and CD79b / B29 polypeptides which are non-covalently associated with membrane bound immunoglobulins on B-cells. CD79a first appears at pre B-cell stage and persists until the plasma cell stage where it is found as an intracellular component. CD79a is found in B-cell lymphomas, in B-cell lines, the majority of acute leukemias of precursor B-cell type and in some myelomas. The CD79a/b heterodimer interacts with at least one tyrosine kinase (Lyn). The induction of tyrosine kinase activity after antigen binding leads to phosphorylation of the CD79a/b dimer, and also of other molecules, thereby initiating intracellular signalling.
