CD274 (Cluster of Differentiation 274) also known as PD-L1 (Programed Death Ligand-1) or B7-H1 is a protein, PD-L1 binds to its receptor, PD-1, found on activated T cells, B cells, and myeloid cells, to modulate activation or inhibition.
The affinity between PD-L1 and PD-1, as defined by the dissociation constant Kd, is 770nM.
Interestingly, PD-L1 also has an appreciable affinity for the costimulatory molecule CD80 (B7-1), but not CD86 (B7-2)
CD80's affinity for PD-L1, 1.4uM, is intermediate between its affinities for CD28 and CTLA-4 (4.0uM and 400nM, respectively).
The related molecule PD-L2 has no such affinity for CD80 or CD86, but shares PD-1 as a receptor (with a stronger Kd of 140nM).
