Functions as a 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 (By similarity).
Activates signaling pathways that lead to the activation of phosphatidylinositol 3-kinase and the mobilization of intracellular Ca2+ 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.
