RNA interference has a role in regulating Drosophila telomeres.

Elena Casacuberta1, Mary-Lou Pardue.   

Abstract

Unlike many other organisms, Drosophila maintains its telomeres by the transposition of retrotransposons to chromosome ends. Recent work shows that proteins in the RNA interference pathway specifically regulate the expression of these retrotransposons and frequency of transposition in germline cells, but do not affect retrotransposon expression or telomere function in the soma.
