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.
The minor allele of a missense SNP in PTPN22 encodes a hematopoietic-specific protein tyrosine phosphatase known as Lyp.
This risk allele is found in approximately 17% of Caucasian individuals in the general population and about 28% of those with rheumatoid arthritis.
It may disrupt the P1 proline-rich motif necessary for interaction with the SH3 domain of CSK (cytoplasmic tyrosine kinase), altering normal T cell activation regulation.
PTPN22 is speculated to act as an effector and/or regulator of CSK in T cells and other hematopoietic cells.
