One function of Lyp is downregulation of T-cell signaling through its interaction with the negative regulatory kinase C-terminal Src tyrosine kinase (Csk). A single nucleotide polymorphism in the PTPN22 gene, C1858T, encodes products with different Csk binding affinities."
M.B. Ladner and associates reported, "Disease association of the PTPN22 1858T allele has been reported in case-control studies of three different autoimmune...
