CD79b molecule, immunoglobulin-associated beta
|Locus||Chr. 17 q23|
CD79 is a transmembrane protein that forms a complex with the B-cell receptor (BCR) and generates a signal following recognition of antigen by the BCR. CD79 is composed of two distinct chains called CD79a and CD79b (formerly known as Ig-alpha and Ig-beta); these form a heterodimer on the surface of a B cell stabilized by disulphide bonding. CD79a and CD79b are both members of the immunoglobulin superfamily. Human CD79a is encoded by the mb-1 gene that is located on chromosome 19, and CD79b is encoded by the B29 gene that located on chromosome 17. Both CD79 chains contain an immunoreceptor tyrosine-based activation motif (ITAM) in their intracellular tails that they use to propogate a signal in a B cell, in a similar manner to CD3 generated signal tranduction observed during T cell receptor activation on T cells.
