Description Not Available
Synonyms
  1. Hematopoietic cell protein-tyrosine phosphatase 70Z-PEP
  2. LyP
  3. Lymphoid phosphatase
  4. PEST-domain phosphatase
  5. PEP
Gene Name PTPN22
Protein Type Enzyme
Biological Properties
General Function Involved in phosphatase activity
Specific 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. 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.
