<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

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).

By similarity1 Publication

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).

Inhibited by pembrolizumab (also named MK-3475 or lambrolizumab), a monoclonal antibody that prevents the interaction with CD274/PDCD1L1 (PubMed:27734966, PubMed:27325296). Inhibited by nivolumab (also named ONO-4538, BMS-936558 or Opdivo), a monoclonal antibody that prevents the interaction with CD274/PDCD1L1 (PubMed:28165004). The interaction with nivolumab is not dependent on glycosylation and depends on a loop at the N-terminus (N-terminal loop, corresponding to residues 25-34) (PubMed:28165004). Targeting the interaction between PDCD1 and CD274/PDCD1L1 with pembrolizumab and nivolumab antibodies has demonstrated great promise as a strategy for controlling and eradicating cancer (PubMed:22658127, PubMed:25034862, PubMed:25399552). Pembrolizumab and nivolumab are used for treatment of patients with advanced melanoma (PubMed:25034862, PubMed:25399552). These antibodies are also effective against other cancers, such as non-small cell lung cancer, renal cell carcinoma, bladder cancer and Hodgkin's lymphoma (PubMed:25034862).6 Publications

Disease descriptionA chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:iA5210FD40C304FB7
