FAMILY
DESCRIPTION
Also known as TRBP2_MOUSE, Tarbp2, Prbp. 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, 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 AGO2. AGO2 bound to the mature miRNA constitutes the minimal RISC and may subsequently dissociate from DICER1 and TARBP2. May also play a role in the production of short interfering RNAs (siRNAs) from double-stranded RNA (dsRNA) by DICER1 (By similarity). Binds in vitro to the PRM1 3'-UTR. Seems to act as a repressor of translation (PubMed:8649414). Self-associates. Component of the RISC loading complex (RLC), or micro-RNA (miRNA) loading complex (miRLC), which is composed of DICER1, AGO2 and TARBP2. Note that the trimeric RLC/miRLC is also referred to as RISC. Interacts with EIF2AK2/PKR and inhibits its protein kinase activity. Interacts with DHX9 (By similarity). Interacts with DICER1 and PRKRA (PubMed:16142218, PubMed:17452327). Interacts with DICER1, AGO2, MOV10, EIF6 and RPL7A (60S ribosome subunit); they form a large RNA-induced silencing complex (RISC) (By similarity).
