Genes

PD-L1 (CD274)

CD274 molecule (CD274; also known as PDL1) is a gene that encodes a protein that is known as programmed cell death 1 ligand 1 (PD-L1). The protein functions in the transmission of the costimulatory signal that is needed for T-cell proliferation. Interaction with the protein inhibits T-cell activation and proliferation. Fusions, missense mutations, nonsense mutations, silent mutations, and frameshift deletions are observed in cancers such as intestinal cancer, skin cancer, and stomach cancer.
