== Disease ==
 +
[https://www.uniprot.org/uniprot/PTN22_HUMAN PTN22_HUMAN] Defects in PTPN22 are a cause of susceptibility to systemic lupus erythematosus (SLE) [MIM:[https://omim.org/entry/152700 152700]. SLE is a chronic, inflammatory and often febrile multisystemic disorder of connective tissue. It affects principally the skin, joints, kidneys and serosal membranes. It is thought to represent a failure of the regulatory mechanisms of the autoimmune system.<ref>PMID:15273934</ref>
 +
== Function ==
 +
[https://www.uniprot.org/uniprot/PTN22_HUMAN PTN22_HUMAN] 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. Associates with and probably dephosphorylates CBL. Dephosphorylates LCK at its activating 'Tyr-394' residue. Dephosphorylates ZAP70 at its activating 'Tyr-493' residue. Dephosphorylates the immune system activator SKAP2.<ref>PMID:16461343</ref> <ref>PMID:18056643</ref> <ref>PMID:19167335</ref> <ref>PMID:21719704</ref>
