... to dpy-21 suppressed rict-1 slow developmental rate. DPY-21 functions canonically in the ten-protein dosage compensation complex (DCC) to downregulate the expression of X-linked genes only in hermaphroditic worms. However, we find that dpy-21 functions outside of its canonical role, as RNAi to dpy-21...

... dosage compensation gene dpy-21 revealed the first molecular differences in the complex that achieves gene-specific versus chromosome-wide repression. dpy-21 mutations, shown here to be null, cause elevated X-linked gene expression in XX animals, but unlike mutations in other dosage compensation genes...
