This protein contains an SH2 domain and a short tail. It associates with the signaling lymphocyte-activation molecule, thereby acting as an inhibitor of this transmembrane protein by blocking the recruitment of the SH2-domain-containing signal-transduction molecule SHP-2 to its docking site. This protein can also bind to other related surface molecules that are expressed on activated T, B and NK cells, thereby modifying signal transduction pathways in these cells. Mutations in this gene cause lymphoproliferative syndrome X-linked type 1 or Duncan disease, a rare immunodeficiency characterized by extreme susceptibility to infection with Epstein-Barr virus, with symptoms including severe mononucleosis and malignant lymphoma. Multiple transcript variants encoding different isoforms have been found for this gene.

In SLAM signaling seems to cooperate with SH2D1B/EAT-2. Initially it has been proposed that association with SLAMF1 prevents SLAMF1 binding to inhibitory effectors including INPP5D/SHIP1 and PTPN11/SHP-2 (PubMed:11806999). However, by simultaneous interactions, recruits FYN which subsequently phosphorylates and activates SLAMF1 (PubMed:12458214). Positively regulates CD244/2B4- and CD84- mediated natural killer (NK) cell functions. Can also promote CD48-, SLAMF6 -, LY9-, and SLAMF7-mediated NK cell activation. In the context of NK cell-mediated cytotoxicity enhances conjugate formation with target cells (By similarity). May also regulate the activity of the neurotrophin receptors NTRK1, NTRK2 and NTRK3. {ECO:0000250|UniProtKB:O88890, ECO:0000269|PubMed:11806999, ECO:0000269|PubMed:12458214, ECO:0000305|PubMed:21219180}. |SH2| |positive regulation of natural killer cell mediated cytotoxicity| |positive regulation of natural killer cell mediated immunity| |regulation of natural killer cell mediated cytotoxicity| |regulation of natural killer cell mediated immunity| |cellular defense response| |SH3/SH2 adaptor activity| |positive regulation of leukocyte mediated cytotoxicity| |positive regulation of cell killing| |regulation of leukocyte mediated cytotoxicity| |regulation of cell killing| |positive regulation of lymphocyte mediated immunity| |positive regulation of leukocyte mediated immunity| |regulation of lymphocyte mediated immunity| |regulation of leukocyte mediated immunity| |positive regulation of immune effector process| |positive regulation of innate immune response| |humoral immune response| |positive regulation of response to biotic stimulus| |regulation of innate immune response| |regulation of immune effector process| |positive regulation of defense response| |positive regulation of multi-organism process| |regulation of response to biotic stimulus| |positive regulation of response to external stimulus| |adaptive immune response| |regulation of defense response| |innate immune response| |regulation of multi-organism process| |positive regulation of immune response| |defense response to other organism| |regulation of response to external stimulus| |cell-cell signaling| |positive regulation of immune system process| |regulation of immune response| |response to other organism| |response to external biotic stimulus| |response to biotic stimulus| |defense response| |regulation of response to stress| |regulation of immune system process| |positive regulation of signal transduction| |positive regulation of cell communication| |positive regulation of signaling| |immune response| \\ === CRISPR Data === No hits were found.
