== Disease ==
[https://www.uniprot.org/uniprot/PDCD1_HUMAN PDCD1_HUMAN] Systemic lupus erythematosus;Multiple sclerosis. Systemic lupus erythematosus 2 (SLEB2) [MIM:[https://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 ==
[https://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>
