HMG-17 is an abundant, nonhistone chromosomal protein that binds preferentially to nucleosomal core particles of mammalian chromatin. The human gene for HMG-17 has been localized to Chromosome (Chr) 1p, but the murine gene has not been previously mapped. Here we identify the murine functional gene, Hmg17, from among more than 25 related sequences (probably processed pseudogenes) and show that it is located on mouse Chr 4, in a region known to have conserved linkage relationships with human Chr 1p. We also report the map locations of 20 additional Hmg17-related sequences on mouse Chrs 1, 2, 3, 5, 7, 8, 9, 13, 15, 16, 17, 18, and X. The multiple, dispersed members of the Hmg17 multigene family can be detected efficiently with a single cDNA probe and provide useful markers for genetic mapping studies in mice.
