Programmed cell death protein 1, also known as PD-1 and CD279, is a protein found on the surface of cells that has a role in regulating the immune system's response to the cells of the human body by down-regulating the immune system and promoting self tolerance by suppressing T cell inflammatory activity.

molecular weight

The protein has a predicted MW of 42.6 kDa. Due to glycosylation, the protein migrates to 65-72 kDa based on Tris-Bis PAGE result.
