Western blot analysis of PTPN22 over-expressed 293 cell line, cotransfected with PTPN22 Validated Chimera RNAi ( Cat # H00026191-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with PTPN22 monoclonal antibody (M01), clone 4F6 (Cat # H00026191-M01 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
This gene encodes of member of the non-receptor class 4 subfamily of the protein-tyrosine phosphatase family. The encoded protein is a lymphoid-specific intracellular phosphatase that associates with the molecular adapter protein CBL and may be involved in regulating CBL function in the T-cell receptor signaling pathway. Mutations in this gene may be associated with a range of autoimmune disorders including Type 1 Diabetes, rheumatoid arthritis, systemic lupus erythematosus and Graves' disease. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq
