| Definitions |
NKG2C, a C-type lectin-like surface receptor, is a member of the NKG2 family and forms heterodimers with CD94 that is expressed on NK cells and a subset of T cells. The CD94/NKG2C killer lectin-like receptor (KLR) perform an important role in immunosurveillance by binding to HLA-E complexes that present peptides derived from the signal sequences of other HLA class I molecules (A, B, C, G), thereby monitoring MHC class I expression. It has been proposed that the activating receptor CD94/NKG2C may contribute with other NK stimulatory molecules (like NKp46, NKp44 and NKp30 and NKG2D) to trigger effector functions when the control exerted by inhibitory receptors is overcome (Guma et al. 2005). NKG2C/CD94 associates with the ITAM-containing adapter protein DAP12 and this leads to cell activation and cytotoxic function. The charged residues in the transmembrane domains of DAP12 and NKG2C are necessary for this interaction (Lanier et al. 1998). NK cells expressing the CD94/NKG2C receptor are preferentially expanded during cytomegalovirus infection in humans (Lopez-Verges et al. 2011) Edited: Garapati, P V, 2012-05-25 Reviewed: Lanier, Lewis L, 2012-08-09 Authored: Garapati, P V, 2012-05-25 |
