Welcome to the KIR BoLA Website, a specialist database for the bovine Killer-cell Immunoglobulin-like Receptors (KIR). The BoLA nomenclature committee is a standing committee of the International Society for Animal Genetics. Its purpose is to collate data on the Bovine Leucocyte Antigens (BoLA) and provide a forum for the analysis and nomenclature of polymorphisms in the genes and proteins of the bovine KIR. Although this committee has not formally met for several years, those members who are still active in the field of bovine MHC continue to oversee nomenclature.


We have listed all the currently known and validated alleles, as nucleotide sequence alignments, for cattle loci in the following tables. The most recent nomenclature is used where possible, and tables of previous equivalents are given. Accession numbers and references for published sequences are listed.
