General annotation (Comments)

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 By similarity.

Cofactor

Binds 2 magnesium or manganese ions per subunit By similarity.

Subunit structure

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. Interacts with BCDIN3D By similarity.

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the helicase family. Dicer subfamily.

Contains 1 Dicer dsRNA-binding fold domain.

Contains 1 DRBM (double-stranded RNA-binding) domain.

Contains 1 helicase ATP-binding domain.

Contains 1 helicase C-terminal domain.

Contains 1 PAZ domain.

Contains 2 RNase III domains.

Caution

It is uncertain whether Met-1 or Met-11 is the initiator.
