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.
Predicted to enable 3'-5'-exoribonuclease activity involved in mature miRNA 3'-end processing. Involved in obsolete negative regulation of transposition, DNA-mediated; olfactory learning; and regulatory ncRNA-mediated post-transcriptional gene silencing. Located in cytosol; mutator focus; and nucleus. Expressed in AWCL; AWCR; and somatic cell. Is an ortholog of human EXD3 (exonuclease 3'-5' domain containing 3).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
