KIR2DL1 (inhibitory KIR)

Short target page →

Inhibitory KIRs are the receptors NK cells use to recognise a person's own HLA-C and stand down. Lirilumab, an antibody that blocks three of them, reached phase 2 but was dropped for blood cancers. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Immunoglobulin-like receptors with long cytoplasmic tails (2DL, 3DL) inhibit through ITIMs; short-tailed KIRs activate. This record stands for the inhibitory KIR2DL group the antibody binds.
