Company description
Programmed cell death protein 1, also known as PD-1 and CD279, is a cell surface receptor that plays an important role in down-regulating the immune system and promoting self-tolerance by suppressing T cell inflammatory activity. In humans, it is encoded by the PDCD1 gene. PD-1 is a member of the immunoglobulin superfamily and is expressed on T-cells and pro-B cells.
