Description: | MSL proteins and noncoding roX RNAs form complexes that bind hundreds of sites along the single male X chromosome to make X-linked gene expression equal in male and female Drosophila. MSL complexes are proposed to up-regulate X-linked genes through site-specific acetylation of histone H4 at Lys16. The roX1 and roX2 RNAs are dissimilar in size and sequence, but are functionally redundant. The roX RNAs are required for normal targeting of the X chromosome, and in their absence MSL complexes bind poorly to the X.
