Received Feb 19; Accepted Apr Two modes of transvection: enhancer action in trans and bypass of a chromatin insulator in cis. Masui, I. Xiao, J. Wu and P. Expression of msl-2 causes assembly of dosage compensation regulators on the X chromosomes and female lethality in Drosophila.

Our data supports the idea of an interaction between Top2 and MLE, but the lack of sex-specificity of rescue argues against a role that is limited to dosage compensation. The Dsx transcription factors coordinate visible somatic differentiation. Queiroz-Machado, and C. Depending on context and binding partners, CTCF can be a transcriptional repressor or an activator [ 21 — 24 ].

Xiao, J.

Mammalian chromosomes occupy nonoverlapping regions, termed chromosome territories, in the nucleus. Coordinated regulation of heterochromatic genes in Drosophila melanogaster males. The different methods by which Top2 activity was reduced in these studies may be responsible for this disparity.

National Center for Biotechnology Information , U. We conclude that mutation of these anti-pairing factors does not lead to feminization of heterochromatin in males. Enzymatic activities within the MSL complex modify chromatin at X-linked genes, leading to increased transcription in male flies.

  • Sex determination in Drosophila is determined by the ratio of X chromosomes to autosomes, where the Y does not play a role. In humans, it is the Y chromosome that determines sex: absence of it causes femaleness and presence causes maleness. In Drosophila, the ratio of X chromosomes to the number of haploid sets of autosomes determines the sex while in humans the presence of the Y chromosome determines maleness.
