Mapping and characterization of the DQ subregion of the ovine MHC.
A map of the ovine MHC class II DQ subregion has been constructed from overlapping cosmid clones. This region consists of two loci linked on a linear tract of 130 kb DNA. Each locus consists of a DQA and a DQB gene in a tail-to-tail orientation. The genes in each locus are transcribed but only those designated DQ1 express class II molecules at the surface of mouse L cells following DNA-mediated gene transfection. The DQA1 and DQB1 genes are separated by 11 kb while the DQA2 and B2 genes are 25 kb apart. The loci are separated by 22 kb.
