Name :
Human PD-L2 protein, ECD (extracellular domain), Fc-fusion, recombinant

Description :
PD-L2 (programmed death ligand 2), also referred to as B7-DC or CD273, is a single pass type I transmembrane glycoprotein that belongs to the B7 family of the Ig superfamily. It was originally identified as a homolog of PD-L1. Like PD-L1 and other B7 family members, PD-L2 contains one Ig V-like and one Ig C-like domain in the extracellular region. Among the family members, they share about 20-25% amino acid identity. PD­L1 and PD­L2 share ~41% amino acid sequence identity and have similar functions. PD-L2 is expressed on antigen presenting cells, placental endothelium and medullary thymic epithelial cells, and can be induced by LPS and INF-γ. PD-L2 and PD-L1 are two ligands for PD-1/CD279, a member of the CD28/CTLA4 family receptors that play critical roles in regulating T cell activation and immune tolerance. Interaction with PD-1, which has a cytoplasmic immunoreceptor tyrosine-based inhibitory motif (ITIM), inhibits T-cell proliferation and cytokine production. PD-L2 is also a dendritic cell molecule with co-stimulatory properties for T cells. The interaction of PD-L2/PD-1 has a 2-6-fold higher affinity than that of B7-H1/PD-1.

Gene Symbol :
The recombinant human PD-L2-Fc fusion is expressed as a 429 amino acid protein consisting of Leu20 – Thr220 region of PD-L2 (UniProt accession #Q9BQ51) and a C-terminal Fc from human IgG1, which exists as a dimer under non-reducing conditions.

NCBI Gene ID :
80380

Uniprot Entry :
