Also known as B7DC, Btdc, CD273, PD-L2, PDCD1L2, PDL2, bA574F11.2, programmed cell death 1 ligand 2

Programmed cell death 1 ligand 2 (also known as PD-L2, B7-DC) is a protein that in humans is encoded by the PDCD1LG2 gene. PDCD1LG2 has also been designated as CD273 (cluster of differentiation 273). PDCD1LG2 is an immune checkpoint receptor ligand which plays a role in negative regulation of the adaptive immune response. PD-L2 is one of two known ligands for Programmed cell death protein 1 (PD-1), the other one being PD-L1 to which it is related by a gene duplication in an ancestor of tetrapod species.
