Distribution of Drosophila insulator proteins Mod(mdg4) and L(3)mbt in Kc cells


ABSTRACT: Here we map the localization of Mod(mdg4), including Mod(mdg4)2.2 specific and Mod(mdg4) common to all isoforms, to chromatin insulators, as well as the lethal-3 malignant brain tumor protein in Drosophila Kc cells. examination of genomic occupancy for Mod(mdg4)2.2, Mod(mdg4)BTB (all isoforms), and L(3)mbt, control samples used for Drosophila Kc were previously described (Wood, Van Bortle et al., 2011 GSE30740)

Several multiprotein DNA complexes capable of insulator activity have been identified in Drosophila melanogaster, yet only CTCF, a highly conserved zinc finger protein, and the transcription factor TFIIIC have been shown to function in mammals. CTCF is involved in diverse nuclear activities, and recent studies suggest that the proteins with which it associates and the DNA sequences that it targets may underlie these various roles. Here we show that the Drosophila homolog of CTCF (dCTCF) aligns i  ...[more]
