| Tissue Specificity | Detected on B cells in spleen, bone marrow, thymus and lymph nodes. Detected on peripheral blood lymphocytes (at protein level). |
| Post Translational Modifications | Phosphorylated on tyrosine following B-cell activation. Phosphorylated on tyrosine residues by LYN. Tyrosine residues are phosphorylated sequentially after activation of the B cell receptor. Phosphorylation of Tyr-522 is extremely rapid, followed by phosphorylation at Tyr-402. In contrast, phosphorylation of Tyr-493 appears more slowly and is more transient, returning rapidly to basal levels. |
| Function | Functions as coreceptor for the B-cell antigen receptor complex (BCR) on B-lymphocytes. Decreases the threshold for activation of downstream signaling pathways and for triggering B-cell responses to antigens. Activates signaling pathways that lead to the activation of phosphatidylinositol 3-kinase and the mobilization of intracellular Ca(2+) stores. Is not required for early steps during B cell differentiation in the blood marrow. Required for normal differentiation of B-1 cells. Required for normal B cell differentiation and proliferation in response to antigen challenges. Required for normal levels of serum immunoglobulins, and for production of high-affinity antibodies in response to antigen challenge. |
