CC -!- FUNCTION: Required for formation of the RNA induced silencing complex
CC (RISC). Component of the RISC loading complex (RLC), also known as the
CC micro-RNA (miRNA) loading complex (miRLC), which is composed of DICER1,
CC AGO2 and TARBP2. Within the RLC/miRLC, DICER1 and TARBP2 are required
CC to process precursor miRNAs (pre-miRNAs) to mature miRNAs and then load
CC them onto AGO2. AGO2 bound to the mature miRNA constitutes the minimal
CC RISC and may subsequently dissociate from DICER1 and TARBP2. May also
CC play a role in the production of short interfering RNAs (siRNAs) from
CC double-stranded RNA (dsRNA) by DICER1. {ECO:0000256|HAMAP-
CC Rule:MF_03034}.
CC -!- SUBUNIT: Self-associates. Component of the RISC loading complex (RLC),
CC or micro-RNA (miRNA) loading complex (miRLC), which is composed of
CC DICER1, AGO2 and TARBP2. Note that the trimeric RLC/miRLC is also
CC referred to as RISC. Interacts with EIF2AK2/PKR and inhibits its
CC protein kinase activity. Interacts with DHX9 and PRKRA. Interacts with
CC DICER1, AGO2, MOV10, EIF6 and RPL7A (60S ribosome subunit); they form a
CC large RNA-induced silencing complex (RISC). {ECO:0000256|HAMAP-
CC Rule:MF_03034}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_03034}.
CC Cytoplasm, perinuclear region {ECO:0000256|HAMAP-Rule:MF_03034}.
CC Nucleus {ECO:0000256|HAMAP-Rule:MF_03034}.
CC -!- SIMILARITY: Belongs to the TARBP2 family. {ECO:0000256|HAMAP-
CC Rule:MF_03034}.
