KIR receptors can distinguish between MHC I allelic variants, which allows them to detect virally infected cells or transformed cells. KIRs are paired receptors, meaning some have activating and others have inhibitory functions; most KIRs are inhibitory: their recognition of MHC molecules suppresses the cytotoxic activity of their NK cell. [5]
Based on their structure there are three different groups of KARS. The first group of receptors is called Natural Cytotoxicity Receptors (NCR), which only includes activation receptors. The two other classes are: Natural Killer Group 2 , which includes activation and inhibition receptors, and some KIRs which do not have an inhibitor role. [7]
An immune receptor (or immunologic receptor) is a receptor, usually on a cell membrane, which binds to a ligand (usually another protein, such as cytokine) and causes a response in the immune system. Types
Killer-cell immunoglobulin-like receptors (KIRs) are transmembrane glycoproteins expressed by natural killer cells and subsets of T cells. The KIR genes are polymorphic and highly homologous and they are found in a cluster on chromosome 19q13.4 within the 1 Mb leukocyte receptor complex (LRC). The gene content of the KIR gene cluster varies ...

Receptors of a particular type are linked to specific cellular biochemical pathways that correspond to the signal. While numerous receptors are found in most cells, each receptor will only bind with ligands of a particular structure. This has been analogously compared to how locks will only accept specifically shaped keys. When a ligand binds ...
