PG - 158-69 LID - 10.1159/000207524 [doi] AB - A series of autosomal insertions of chromosomal fragments derived from around the X linked white eye color locus have been examined for male specific lethal (MSL) complex binding using both immunostaining and fluorescence in situ hybridization (FISH) techniques. The results show that the transposing elements (TEs) composed of several genes in the white region (3C2-3C5) do not recruit the MSL complex when inserted into an autosome. The same result is found for the Tp(1:3)wzh insertion, a fragment of the X chromosome inserted into the third chromosome. Two other insertions, Dp(1:2)w70h (3A7-3C2-3) and Dp(1:2)51b (3C2-3D6), which extend more distally or proximally beyond the TE insertion, respectively, display a binding pattern of the MSL complex at the autosomal location. These insertions were also examined in females ectopically expressing MSL-2 and show similar binding activity. In addition, the Tp(3:1)O5 transposition strain containing an autosomal segment in the X chromosome was examined for spreading of the MSL complex. Limited spreading of the MSL complex into autosomal regions was indicated by immunostaining and FISH. This spreading was further confirmed by chromatin immunoprecipitation of the MSL complex covering the autosomal sequences. CI - Copyright 2009 S. Karger AG, Basel.
