| - | + | [https://www.uniprot.org/uniprot/TRBP2_HUMAN TRBP2_HUMAN] 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. May also play a role in the production of short interfering RNAs (siRNAs) from double-stranded RNA (dsRNA) by DICER1. Binds to the HIV-1 TAR RNA which is located in the long terminal repeat (LTR) of HIV-1, and stimulates translation of TAR-containing RNAs. This is achieved in part at least by binding to and inhibiting EIF2AK2/PKR, thereby reducing phosphorylation and inhibition of EIF2S1/eIF-2-alpha. May also promote translation of TAR-containing RNAs independently of EIF2AK2/PKR.<ref>PMID:12475984</ref> <ref>PMID:16271387</ref> <ref>PMID:16142218</ref> <ref>PMID:16357216</ref> <ref>PMID:15973356</ref> <ref>PMID:16424907</ref> <ref>PMID:17452327</ref> <ref>PMID:18178619</ref> <ref>PMID:19219043</ref> | |
