target relevance
Programmed cell death protein 1, also known as PD-1 and CD279 , is a protein found on the surface of cells that has a role in regulating the immune system's response to the cells of the human body by down-regulating the immune system and promoting self tolerance by suppressing T cell inflammatory activity.
Protein names Programmed cell death protein 1 (Protein PD-1) (hPD-1) (CD antigen CD279)
Mass 31647Da
Function Inhibitory receptor on antigen activated T-cells that plays a critical role in induction and maintenance of immune tolerance to self (PubMed:21276005). Delivers inhibitory signals upon binding to ligands CD274/PDCD1L1 and CD273/PDCD1LG2 (PubMed:21276005). Following T-cell receptor (TCR) engagement, PDCD1 associates with CD3-TCR in the immunological synapse and directly inhibits T-cell activation (By similarity). 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 (By similarity). {ECO:0000250\|UniProtKB:Q02242, ECO:0000269\|PubMed:21276005}.; The PDCD1-mediated inhibitory pathway is exploited by tumors to attenuate anti-tumor immunity and escape destruction by the immune system, thereby facilitating tumor survival (PubMed:28951311). The interaction with CD274/PDCD1L1 inhibits cytotoxic T lymphocytes (CTLs) effector function (PubMed:28951311). The blockage of the PDCD1-mediated pathway results in the reversal of the exhausted T-cell phenotype and the normalization of the anti-tumor response, providing a rationale for cancer immunotherapy (PubMed:22658127, PubMed:25034862, PubMed:25399552). {ECO:0000269\|PubMed:22658127, ECO:0000269\|PubMed:25034862, ECO:0000269\|PubMed:25399552, ECO:0000303\|PubMed:28951311}.
Subellular location Cell membrane {ECO:0000269\|PubMed:30487606}; Single-pass type I membrane protein.
Structure Monomer (PubMed:26602187). Interacts with CD274/PDCD1L1 (PubMed:26602187). Interacts with CD273/PDCD1LG2 (By similarity). Interacts with FBXO38; leading to ubiquitination and degradation of PDCD1 by the proteasome (PubMed:30487606). {ECO:0000250\|UniProtKB:Q02242, ECO:0000269\|PubMed:26602187, ECO:0000269\|PubMed:30487606}.
Post-translational modification Ubiquitinated at Lys-233 by the SCF(FBXO38) complex, leading to its proteasomal degradation (PubMed:30487606). Ubiquitinated via 'Lys-48'-linked polyubiquitin chains (PubMed:30487606). {ECO:0000269\|PubMed:30487606}.; Tyrosine phosphorylated at Tyr-223 (within ITIM motif) and Tyr-248 (ITSM motif) upon ligand binding. Phosphorylation at Tyr-248 promotes 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. {ECO:0000250\|UniProtKB:Q02242}.; N-glycosylation at Asn-58 contains at least two N-acetylglucosamine units and one fucose (PubMed:28165004). N-glycosylation does not affect binding to nivolumab drug (PubMed:28165004). {ECO:0000269\|PubMed:28165004}.
