背景介绍
Acts as negative regulator of T-cell receptor(TCR) signaling by direct dephosphorylation of the Src family kinases LCK and FYN, ITAMs of the TCRz/CD3 complex, as well as ZAP70, VAV, VCP and other key signaling molecules(PubMed:16461343, PubMed:18056643). Associates with and probably dephosphorylates CBL. Dephosphorylates LCK at its activating 'Tyr-394' residue(PubMed:21719704). Dephosphorylates ZAP70 at its activating 'Tyr-493' residue(PubMed:16461343). Dephosphorylates the immune system activator SKAP2(PubMed:21719704). Positively regulates toll-like receptor(TLR)-induced type 1 interferon production(PubMed:23871208). Promotes host antiviral responses mediated by type 1 interferon(By similarity). Regulates NOD2-induced pro-inflammatory cytokine secretion and autophagy(PubMed:23991106).
