mut-7 encodes a homolog of RnaseD that represses transposition of Tc1, Tc3, Tc4, and Tc5, perhaps by degrading transposon-specific messages; also affects sperm development, sensitivity to RNAi of mainly germline expressed genes, silencing of some germline transgenes, X chromosome loss, and is required for cosuppression (functional silencing of chromosomal loci induced by transgenes) and for silencing induced by antisense RNA oligomers; cellular fractionation experiments indicate that MUT-7 is expressed in adult worms, and resides in a complex in both the cytosol and nucleus; in the cytosolic complex, MUT-7 interacts with RDE-2, a novel protein also required for RNA interference.
