Mapping of PEG11 and PEG11AS transcripts by ribonuclease protection assay. A) A diagram of the PEG11 open reading frame (black arrow) and the position of the five riboprobes are shown. The PEG11 open reading frame extends from base 191859 to 187858 on the complementary strand of AF354168. B) Ribonuclease protection assays using PEG11AS (left column) and PEG11 (right column) are shown using total RNA from the gluteus medius (GM) and the supraspinatus (SP) muscles for each of the four possible genotypes. The genotypes are given with the maternal allele first followed by the paternal allele. The CLPG allele has been abbreviated to C and the paternal heterozygote that demonstrates the callipyge phenotype is indicated with an asterisk (*). Yeast RNA with RNase treatment (Y+) and without RNase treatment (Y-) are shown as controls. A black arrow indicates the RNA fragments protected by each of the five RNA probes. Some full-length probes for C and E that could not be completely eliminated by RNase digestion are present in both muscle RNA samples and the yeast RNA control (Y+).
