A new enhancer of position-effect variegation in Drosophila melanogaster encodes a putative RNA helicase that binds chromosomes and is regulated by the cell cycle.

Abstract

In Drosophila melanogaster, position-effect variegation of the white gene has been a useful phenomenon by which to study chromosome structure and the genes that modify it. We have identified a new enhancer of variegation locus, Dmrnahel (hel). Deletion of mutation of hel enhances white variegation, and this can be reversed by a transformed copy of hel+. In… (More)
