背景	Programmed cell death protein 1 (CD279/PD-1) is a ~31 kDa protein. Inhibitory receptor on antigen activated T-cells that plays a critical role in induction and maintenance of immune tolerance to self. Delivers inhibitory signals upon binding to ligands CD274/PDCD1L1 and CD273/PDCD1LG2. Following T-cell receptor (TCR) engagement, PDCD1 associates with TCR-CD3 in the immunological synapse and directly inhibits T-cell activation. Suppresses T-cell activation through the recruitment of PTPN11/SHP-2: following ligand-binding, PDCD1 is phosphorylated within the ITSM motif, leading to the recruitment of the protein tyrosine phosphatase PTPN11/SHP-2 that mediates dephosphorylation of key TCR proximal signaling molecules, such as ZAP70, PRKCQ/PKCtheta and CD247/CD3zeta. CD279 is the therapeutic target of pembrolizumab (Keytruda) and nivolumab (Opdivo). 1. Fife, BT. et al. (2011) Annals of the New York Academy of Sciences 1217, 45-59. PMID: 21276005 2.
