Background

Lymphoid phosphatase (Lyp), also called LyPTP, Protein Tyrosine Phosphatase, Nonreceptor-type 22 (PTPN22), and PEST-domain Phosphatase (PEP), dephosphorylates tyrosine residues in proteins. Found primarily in bone marrow and lymphoid cell lines, an R620W gain-of-function mutation in Lyp has been associated with susceptibility to autoimmune diseases such as type I diabetes, rheumatoid arthritis, and lupus erythematosus. Mature PEP knockout mice have an excess of CD8 positive T-cells and an exaggerated antigen-induced proliferative response.
