Protein Information
Name PTPN22
Synonyms PTPN8
Function 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).
Cellular Location Cytoplasm.
Tissue Location Expressed in bone marrow, B and T-cells, PBMCs, natural killer cells, monocytes, dendritic cells and neutrophils (PubMed:15208781). Both isoform 1 and 4 are predominantly expressed in lymphoid tissues and cells. Isoform 1 is expressed in thymocytes and both mature B and T-cells

This gene encodes of member of the non-receptor class 4subfamily of the protein-tyrosine phosphatase family. The encodedprotein is a lymphoid-specific intracellular phosphatase thatassociates with the molecular adapter protein CBL and may beinvolved in regulating CBL function in the T-cell receptorsignaling pathway. Mutations in this gene may be associated with arange of autoimmune disorders including Type 1 Diabetes, rheumatoidarthritis, systemic lupus erythematosus and Graves' disease.Alternatively spliced transcript variants encoding distinctisoforms have been described.
