CD79b - A Signal Transduction Component of the B-cell Receptor

The B-cell antigen receptor (BCR) is a complex multimeric aggregate that includes the following key noncovalently-bound components: antigen-specific surface immunoglobulin (Ig), CD79a (Ig-alpha), and CD79b (Ig-beta). BCR signaling is a pivotal pathway in tumorigenesis. The CD79 signaling subunits ar ...

Major Histocompatibility Complex (MHC) Class I

The products of MHC genes are antigen-presenting molecules (APMs) designed for antigen fragment (peptide) presentation to the T-cell receptor. In particular, MHC Class I molecules play a key role in the immune system by presenting endogenously synthesized peptides derived from the endoplasmic reticu ...
