Target Information
The protein tyrosine phosphatase PTPN22 (also known as PTP22, LYP, PEP, formerly PTPN8) is a genetic variant associated with increased risk of autoimmune diseases such as type 1 diabetes and rheumatoid arthritis.
A missense SNP in PTPN22 encodes a hematopoietic-specific phosphatase known as Lyp, with the risk allele found in approximately 17% of the general Caucasian population and 28% of rheumatoid arthritis patients.
This variant may disrupt the P1 proline-rich motif critical for interaction with the SH3 domain of CSK (cytoplasmic tyrosine kinase), potentially altering normal negative regulation of T cell activation.
The CSK–PTPN22 interaction is highly specific, suggesting that PTPN22 may act as an effector and/or regulator of CSK in T cells and other hematopoietic cells.
