cofactor:Binds 2 magnesium or manganese ions per subunit. ,Function:Required for formation of the RNA induced silencing complex (RISC) . Component of the RISC loading complex (RLC) , also known as the micro-RNA (miRNA) loading complex (miRLC) , which is composed of DICER1 , EIF2C2/AGO2 and TARBP2. Within the RLC/miRLC , DICER1 and TARBP2 are required to process precursor miRNAs (pre-miRNAs) to mature miRNAs and then load them onto EIF2C2/AGO2. EIF2C2/AGO2 bound to the mature miRNA constitutes the minimal RISC and may subsequently dissociate from DICER1 and TARBP2. Also cleaves double-stranded RNA to produce short interfering RNAs (siRNAs) which target the selective destruction of complementary RNAs. ,online information:The dark side of RNA -Issue 87 of October 2007 ,similarity:Belongs to the helicase family. Dicer subfamily. ,similarity:Contains 1 Dicer dsRNA-binding fold domain. ,similarity:Contains 1 DRBM (double-stranded RNA-binding) domain. ,similarity:Contains 1 helicase ATP-binding domain. ,similarity:Contains 1 helicase C-terminal domain. ,similarity:Contains 1 PAZ domain. ,similarity:Contains 2 RNase III domains. ,subunit:Component of the RISC loading complex (RLC) , or micro-RNA (miRNA) loading complex (miRLC) , which is composed of DICER1 , EIF2C2/AGO2 and TARBP2. Note that the trimeric RLC/miRLC is also referred to as RISC. Interacts with DHX9 , EIF2C1 , PIWIL1 and PRKRA. Associates with the 60S ribosome. ,
