The gene PDCD1 (programmed cell death protein 1) is mapped to human chromosome 2q37. The encoded protein belongs to the CD28 superfamily. It interacts with its ligands PD-L1/PD-L2 (programmed death-ligands).

Biochem Physiol Actions: PDCD1 (programmed cell death protein 1) plays an important role in the immune regulation by working as a negative co-stimulatory factor. It suppresses working and multiplication of the T cells, thereby reducing the release of IL-2 (interleukin-2), IL-10 and IFN-? (interferon ?). In the presence of tumor microenvironment, PDCD1 along with its ligand modulates T effector functioning, thereby protecting cancer cells from immune-associated rejection. Mutation in this gene is associated with symptoms and progression of multiple sclerosis. Mutation in it are also linked with susceptibility to systemic lupus erythematosus.
