CD79a (Ig alpha, MB1) forms disulfide-linked heterodimer with CD79b (Ig beta).
They both are transmembrane proteins with extended cytoplasmic domains containing immunoreceptor tyrosine activation motives (ITAMs), and together with cell surface immunoglobulin they constitute B-cell antigen-specific receptor (BCR).
CD79a and b are the first components of BCR that are expressed developmentally.
They appear on pro-B cells in association with the endoplasmic reticulum chaperone calnexin.
Subsequently, in pre-B cells, CD79 heterodimer is associated with lambda5-VpreB surrogate immunoglobulin and later with antigen-specific surface immunoglobulins.
At the plasma cell stage, CD79a is present as an intracellular component.
CD79a/b complex interacts with Src-family tyrosine kinase Lyn, which phosphorylates its cytoplasmic ITAM motives to form docking sites for downstream signaling.
