Summary: Enables RNA binding activity and endoribonuclease activity. Involved in embryo development; gene silencing by RNA; and nematode larval development. Located in cytoplasm. Part of RISC complex. Is expressed in several structures, including gonad; hypodermis; neurons; somatic cell; and ventral nerve cord. Orthologous to several human genes including AGO2 (argonaute RISC catalytic component 2). [provided by Alliance of Genome Resources, Apr 2022]
