Alternative Names
Melanoma Cell Adhesion Molecule; S-Endo 1 Endothelial-Associated Antigen; Melanoma-Associated Antigen MUC18; Cell Surface Glycoprotein P1H12; Melanoma-Associated Antigen A32; Gicerin;
Function
Required in cooperation with CD79A for initiation of the signal transduction cascade activated by the B-cell antigen receptor complex (BCR) which leads to internalization of the complex, trafficking to late endosomes and antigen presentation. Enhances phosphorylation of CD79A, possibly by recruiting kinases which phosphorylate CD79A or by recruiting proteins which bind to CD79A and protect it from dephosphorylation.
Biological Process
Adaptive immune response Source: UniProtKB-KW
B cell differentiation Source: GO_Central
B cell receptor signaling pathway Source: GO_Central
Immune response Source: ProtInc
Signal transduction Source: ProtInc
Cellular Location
Cell membrane. Following antigen binding, the BCR has been shown to translocate from detergent-soluble regions of the cell membrane to lipid rafts although signal transduction through the complex can also occur outside lipid rafts.
Involvement in disease
Agammaglobulinemia 6, autosomal recessive (AGM6): A primary immunodeficiency characterized by profoundly low or absent serum antibodies and low or absent circulating B-cells due to an early block of B-cell development. Affected individuals develop severe infections in the first years of life.
Topology
Extracellular: 29-159
Helical: 160-180
Cytoplasmic: 181-229
PTM
Phosphorylated on tyrosine upon B-cell activation by SRC-type Tyr-kinases such as BLK, LYN and SYK.
