背景

Background: NKG2C/CD159c

Human NKG2C (NK cell Group 2 isoform C; Killer cell lectin-like receptor subfamily C, member 2) is a member of the C-type lectin-like superfamily of proteins. Natural killer (NK) receptors are expressed in both NK cells and cytotoxic CD8+ T cells and have both activating and inhibitory members (1-3). Regulation of the balance between the activating and inhibitory receptors is important and lack of such regulation has been implicated in autoimmunity (4). The NKG2 family includes seven receptors: NKG2A, -B, -C, -D, -E, -F, and -H, which is the longer isoform of NKG2E. Except for NKG2D and NKG2F, the NKG2 family members form heterodimers with CD94 (5, 6). NKG2C interacts with the adapter molecule DAP12 and acts as activating receptor when heterodimerized with CD94 (7). Human NKG2C is synthesized as a 231 amino acid (aa) protein that includes a 70 aa cytoplasmic domain, a 23 aa transmembrane segment, and a 138 aa extracellular domain (ECD). Within the ECD, human NKG2C shares 40% sequence identity with mouse NKG2C. NKG2C-CD94 heterodimers bind to the widely expressed nonclassical MHC-I molecule, HLA-E (Qa-1b in mouse), which presents a peptide derived from the signal peptide of classical MHC-I molecules (8, 9). Triggering the NKG2C-CD94 complex may activate the cytolytic activity and cytokine production of NK and CD8+ T cells (8, 10). Human cytomegalovirus (HCMV) infection promotes the differentiation and expansion of NKG2C+ NK cell subsets, possibly involving a cognate interaction of CD94/NKG2C with ligand(s) displayed by HCMV‑infected cells (11, 12). MAB1381 (clone 134522) displays potent agonistic activity and also blocks the binding of the NKG2C/CD94 heterodimer to HLA-E tetramers (13-15).
