function:May function as an activating coreceptor in B cells. May function in B cells activation and differentiation.,induction:Down-regulated in activated B cells.,PTM:Phosphorylated on tyrosines upon activation.,similarity:Contains 3 Ig-like C2-type (immunoglobulin-like) domains.,tissue specificity:Primarily expressed in secondary lymphoid tissues by mature subsets of B cells. Detected in spleen, lymph node, heart, skeletal muscle, kidney, liver and placenta. Specifically expressed by mature B lineage cells with higher expression in naive versus memory B cells (at protein level).,
