Background

Protein tyrosine phosphatase, non-receptor type 22 (lymphoid), also known as PTPN22, is a protein that in humans is encoded by the PTPN22 gene. This gene encodes of member of the non-receptor class 4 subfamily of the protein-tyrosine phosphatase family. The encoded protein is a lymphoid-specific intracellular phosphatase that associates with the molecular adapter protein CBL and may be involved in regulating CBL function in the T-cell receptor signaling pathway. Mutations in this gene may be associated with a range of autoimmune disorders including Type 1 Diabetes, rheumatoid arthritis, systemic lupus erythematosus and Graves' disease. Alternatively spliced transcript variants encoding distinct isoforms have been described.

Function

Acts as negative regulator of T-cell receptor (TCR) signaling by 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 (By similarity) . Associates with and probably dephosphorylates CBL (By similarity) . Dephosphorylates LCK at its activating 'Tyr-394' residue (By similarity) . Dephosphorylates ZAP70 at its activating 'Tyr-492' residue (By similarity) . Dephosphorylates the immune system activator SKAP2 (By similarity) . Positively regulates toll-like receptor (TLR) -induced type 1 interferon production (PubMed:23871208) . Promotes host antiviral responses mediated by type 1 interferon (PubMed:23871208) . Regulates NOD2-induced pro- inflammatory cytokine secretion and autophagy (PubMed:23991106) .
