Killer cell immunoglobulin-like receptors (KIRs) are transmembrane glycoproteins expressed by natural killer cells andsubsets of T cells. The KIR genes are polymorphic and highly homologous and they are found in a cluster on chromosome19q13.4 within the 1 Mb leukocyte receptor complex (LRC). The gene content of the KIR gene cluster varies amonghaplotypes, although several "framework" genes are found in all haplotypes (KIR3DL3, KIR3DP1, KIR3DL4,KIR3DL2). The KIR proteins are classified by the number of extracellular immunoglobulin domains (2D or 3D) and bywhether they have a long (L) or short (S) cytoplasmic domain. KIR proteins with the long cytoplasmic domain transduceinhibitory signals upon ligand binding via an immune tyrosine-based inhibitory motif (ITIM), while KIR proteins withthe short cytoplasmic domain lack the ITIM motif and instead associate with the TYRO protein tyrosine kinase bindingprotein to transduce activating signals. The ligands for several KIR proteins are subsets of HLA class I molecules;thus, KIR proteins are thought to play an important role in regulation of the immune response. This gene is one of the"framework" loci that is present on all haplotypes. This gene is considered to be a pseudogene based on theabsence of transcription and it lacks several functional domains compared to other killer cell immunoglobulin-likereceptors.
