Programmed Cell Death 1 Receptor
PD 1 Receptor
Programmed Cell Death 1 Protein
An inhibitory T-lymphocyte receptor that has specificity for CD274 ANTIGEN and PROGRAMMED CELL DEATH 1 LIGAND 2 PROTEIN. Signaling by the receptor limits T cell proliferation and INTERFERON GAMMA synthesis. The receptor also may play an essential role in the regulatory pathway that induces PERIPHERAL TOLERANCE.
