== Disease ==
[[http://www.uniprot.org/uniprot/PDCD1_HUMAN PDCD1_HUMAN]] Systemic lupus erythematosus;Multiple sclerosis. Systemic lupus erythematosus 2 (SLEB2) [MIM:[http://omim.org/entry/605218 605218]]: A 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. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.<ref>PMID:12402038</ref>  
== Function ==
[[http://www.uniprot.org/uniprot/PD1L1_HUMAN PD1L1_HUMAN]] Involved in the costimulatory signal, essential for T-cell proliferation and production of IL10 and IFNG, in an IL2-dependent and a PDCD1-independent manner. Interaction with PDCD1 inhibits T-cell proliferation and cytokine production.<ref>PMID:10581077</ref> <ref>PMID:11015443</ref>  [[http://www.uniprot.org/uniprot/PDCD1_HUMAN PDCD1_HUMAN]] Inhibitory cell surface receptor involved in the regulation of T-cell function during immunity and tolerance. Upon ligand binding, inhibits T-cell effector functions in an antigen-specific manner. Possible cell death inducer, in association with other factors.<ref>PMID:21276005</ref>

== Publication Abstract from PubMed ==
Targeting the PD-1/PD-L1 immunologic checkpoint with monoclonal antibodies has recently provided breakthrough progress in the treatment of melanoma, non-small cell lung cancer, and other types of cancer. Small-molecule drugs interfering with this pathway are highly awaited, but their development is hindered by insufficient structural information. This study reveals the molecular details of the human PD-1/PD-L1 interaction based on an X-ray structure of the complex. First, it is shown that the ligand binding to human PD-1 is associated with significant plasticity within the receptor. Second, a detailed molecular map of the interaction surface is provided, allowing definition of the regions within both interacting partners that may likely be targeted by small molecules.
