Enables mRNA 3'-UTR binding activity. Involved in several processes, including negative regulation of Ras protein signal transduction; negative regulation of gene expression; and regulation of development, heterochronic. Part of RISC complex. Expressed in several structures, including gonad; hypodermis; somatic nervous system; touch receptor neurons; and vulval precursor cell. Used to study cancer.
Enables ribonuclease III activity. Involved in primary miRNA processing and sexual reproduction. Predicted to be located in nucleus. Predicted to be part of microprocessor complex. Is an ortholog of human DROSHA (drosha ribonuclease III).
