CD274 / B7-H1 / PD-L1

CD274 molecule

CD274, also known as B7-H1 and PD-L1, a cell surface glycoprotein, is a member of the B7 family of co-stimulatory molecules. CD274 is expressed constitutively on macrophages and dendritic cells, and is induced on activated T-cells, B-cells, endothelial cells and epithelial cells in response to interferons. CD274 has dual functions: inhibition of activated effector T cells and co-stimulation of naïve T cells. It inhibits proliferation of activated T cells via ligation to the co-inhibitory molecule CD279 (programmed death-1; PD-1) leading to the secretion of the regulatory cytokine interleukin-10. Expression of CD274 in tumor cells is considered to be prognostic in many types of human malignancies, including colon cancer and renal cell carcinoma.

Gene Name:	CD274 molecule
Synonyms:	CD274, B7-H, B7 homolog 1, B7-H1, B7H1, CD274 molecule, CD274 antigen, PDCD1 ligand 1, PDL1, PD-L1, PDCD1L1, PDCD1LG1, Programmed death ligand 1
Target Sequences:	NM_014143 NP_054862.1 Q9NZQ7
