Domain:The most membrane-proximal SH2-binding motif interacts with SH2 domain of SH2D1A and does not need to be phosphorylated on tyrosine residues. ,Function:High-affinity self-ligand important in bidirectional T-cell to B-cell stimulation. SLAM-induced signal-transduction events in T-lymphocytes are different from those in B-cells. Two modes of SLAM signaling are likely to exist: one in which the inhibitor SH2D1A acts as a negative regulator and another in which protein-tyrosine phosphatase 2C (PTPN11) -dependent signal transduction operates. ,PTM:Phosphorylated by FYN. ,similarity:Contains 1 Ig-like C2-type (immunoglobulin-like) domain. ,similarity:Contains 1 Ig-like V-type (immunoglobulin-like) domain. ,subcellular location:Present on the surface of B-cells and T-cells. ,subunit:Its cytoplasmic domain interacts with SH2 domain protein 1A (SH2D1A) , and with PTPN11. Interacts with INPP5D/SHIP1. Binds to Measles virus HN protein and acts as a receptor for this virus. ,tissue specificity:Constitutively expressed on peripheral blood memory T-cells , T-cell clones , immature thymocytes , and a proportion of B-cells , and is rapidely induced on naive T-cells after activation. ,
