Killer-cell immunoglobulin-like receptor (KIR) nomenclature report, 2002

During discussion at the WHO Nomenclature Committee for Factors of the HLA System meeting in Victoria, Canada in May 2002, it was decided to form a subcommittee to co-ordinate the naming of alleles of the genes encoding the killer-cell immunoglobulin-like receptors (KIR) (Marsh et al. 2002). These genes are encoded on chromosome 19 (19q13.4) and have varying degrees of polymorphism. The receptors encoded by the KIR genes are expressed by natural killer (NK) cells and a subset of T cells and some of them have been shown to have specificity for determinants of HLA class I molecules. The extracellular ligand-binding part of KIR consists of two or three immunoglobulin(Ig-) like domains. The discussions which took place in Victoria are further to earlier discussions on KIR nomenclature at the NK Polymorphism meeting (27–29 July 2001) in Cambridge, UK. In addition a request has been made by the International Union of Immunological Societies (IUIS) to provide a standardised nomenclature for the expressed protein products of the KIR genes.

Human KIR sequences 2003

We have compiled the nucleotide sequences and their amino acid translations from a total of 89 Killer Immunoglobulin-like Receptor (KIR) alleles, derived from 17 different KIR genes. The alignments use the KIR3DL2*001 allele as a reference sequence. Each of the KIR sequences included in these alignments has been checked and where discrepancies have arisen between reported sequences, the original authors have been contacted where possible, and necessary amendments to published sequences have been incorporated into this alignment. Future sequencing may identify errors in this list and we would welcome any evidence that helps to maintain the accuracy of this compilation.
