83-5957-67　CD79a (CD 79a, BCR alpha, Ig-alpha, MB-1, IGA, B Cell Antigen Receptor Complex Associated Protein alpha Chain precursor, CD79A Antigen) (FITC) 100Tests　C2431-14A5

特徴

• 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.
