Lymphocyte-specific protein tyrosine kinase (Lck) is crucial for signaling from the T cell receptor (TCR) and is controlled through tyrosine phosphorylations. Phosphorylated Tyr505 (pTyr505) promotes a closed, inactive conformation of Lck, while pTyr394 is critical for kinase activity. Additionally,...

Protein Tyrosine Phosphatase Non-receptor type 22 (PTPN22) is encoded by a major autoimmunity gene and is a known inhibitor of T cell receptor (TCR) signaling. PTPN22 Ser449 is a novel phosphorylation site. Here we used optimized coding sequences (CDS) of PTPN22 WT or S449A eukaryotic expression vec...
