We present a linkage map of intracisternal A-particle (IAP) proviral loci. The IAP family consists of 2000 endogenous proviral elements that are widely dispersed in the mouse genome. The map was constructed by using an interspecific backcross and markers defined by oligonucleotide probes specific for subclasses of expressed IAP elements. In genomic DNA from C57BL/6J mouse, these probes each detected from 12 to 44 HindIII restriction fragments that represent junctions between proviral and 5'-flanking DNA. The fragments have characteristic strain distribution patterns (SDPs) that are particularly polymorphic in the DNAs of C57BL/6J and Mus spretus mice used for the backcross. IAP loci were placed on the map by comparison of their distribution patterns with those of known genetic markers in the backcross. The map includes 51 IAP loci that have not been previously mapped and 23 IAP proviruses that had been previously mapped in recombinant inbred (RI) strains. Comparable map positions were obtained with the IAP markers in the interspecific backcross and the RI strains. The mapped IAP loci were widely dispersed on the X Chromosome (Chr) and all of the autosomes except Chrs 9 and 19, providing useful genetic markers for linkage studies.
