Functioni

Cytoplasmic adapter regulating receptors of the signaling lymphocytic activation molecule (SLAM) family such as CD84, SLAMF1, LY9 and CD244 (PubMed:11689425). In SLAM signaling seems to cooperate with SH2D1A/SAP. Plays a role in regulation of effector functions of natural killer (NK) cells by controlling signal transduction through CD244/2B4 without effecting its tyrosine phosphorylation; downstream signaling involves PLCG1 and ERK activation (PubMed:24687958). Activation of SLAMF7-mediated NK cell function does not effect receptor tyrosine phosphorylation but distal signaling (By similarity). In the context of NK cell-mediated cytotoxicity does not enhance conjugate formation with target cells but stimulates polarization of the microtubule-organizing center and cytotoxic granules toward the NK cell synapse (PubMed:24687958). Negatively regulates CD40-induced cytokine production in dendritic cells downstream of SLAM family receptors probably by inducing activation of the PI3K pathway to inhibit p38 MAPK and JNK activation (By similarity).By similarity1 Publication2 Publications

Interactioni

Subunit structurei

Binds to the phosphorylated receptors CD84, SLAMF1, LY9 and CD244. Does not bind to non-phosphorylated SLAMF1 (PubMed:11689425). Interacts with SLAMF7 (via ITSM phosphorylated on 'Tyr-304'). Interacts with Src kinases HCK, LYN, FYN, FGR and LCK (via kinase domains) (By similarity). Interacts (phosphorylated at Tyr-127) with PLCG1.By similarity2 Publications
