Fifty-million-year-old polymorphism at an immunoglobulin variable region gene locus in the rabbit evolutionary lineage
17 Aug 1999
Abstract excerpt
The Ig heavy chain variable region (V(H)) genes encode the antigen-binding regions of antibodies. The rabbit genome contains more than 100 V(H) genes, but only one (V(H)1) is preferentially used in the VDJ gene rearrangement. Three highly divergent alleles occur at this V(H)1 locus in most rabbit populations. These three V(H) alleles are also present in snowshoe hare populations, indicating that the polymorphism...
