Natl. Acad. Sci. U.S.A. 115:E620-E629(2018). CC -!- FUNCTION: Required for RNA-mediated gene silencing (RNAi) by the CC RNA-induced silencing complex (RISC). The 'minimal RISC' appears CC to include AGO2 bound to a short guide RNA such as a microRNA CC (miRNA) or short interfering RNA (siRNA). These guide RNAs direct CC RISC to complementary mRNAs that are targets for RISC-mediated CC gene silencing. The precise mechanism of gene silencing depends on CC the degree of complementarity between the miRNA or siRNA and its CC target. Binding of RISC to a perfectly complementary mRNA CC generally results in silencing due to endonucleolytic cleavage of CC the mRNA specifically by AGO2. Binding of RISC to a partially CC complementary mRNA results in silencing through inhibition of CC translation, and this is independent of endonuclease activity. May CC inhibit translation initiation by binding to the 7-methylguanosine CC cap, thereby preventing the recruitment of the translation CC initiation factor eIF4-E. May also inhibit translation initiation CC via interaction with EIF6, which itself binds to the 60S ribosomal CC subunit and prevents its association with the 40S ribosomal CC subunit. The inhibition of translational initiation leads to the CC accumulation of the affected mRNA in cytoplasmic processing bodies CC (P-bodies), where mRNA degradation may subsequently occur. In some CC cases RISC-mediated translational repression is also observed for CC miRNAs that perfectly match the 3' untranslated region (3'-UTR). CC Can also up-regulate the translation of specific mRNAs under CC certain growth conditions. Binds to the AU element of the 3'-UTR CC of the TNF (TNF-alpha) mRNA and up-regulates translation under CC conditions of serum starvation. Also required for transcriptional CC gene silencing (TGS), in which short RNAs known as antigene RNAs CC or agRNAs direct the transcriptional repression of complementary CC promoter regions. Regulates lymphoid and erythroid development and CC function, and this is independent of endonuclease activity.

Together, DICER1, AGO2 and TARBP2 constitute the trimeric CC RISC loading complex (RLC), or micro-RNA (miRNA) loading complex CC (miRLC). Within the RLC/miRLC, DICER1 and TARBP2 are required to CC process precursor miRNAs (pre-miRNAs) to mature miRNAs and then CC load them onto AGO2. AGO2 bound to the mature miRNA constitutes CC the minimal RISC and may subsequently dissociate from DICER1 and CC TARBP2. Note however that the term RISC has also been used to CC describe the trimeric RLC/miRLC. The formation of RISC complexes CC containing siRNAs rather than miRNAs appears to occur CC independently of DICER1 (PubMed:16357216). Interacts with AGO1. CC Also interacts with DDB1, DDX5, DDX6, DDX20, DHX30, DHX36, DDX47, CC DHX9, ELAVL, FXR1, GEMIN4, HNRNPF, IGF2BP1, ILF3, IMP8, MATR3, CC PABPC1, PRMT5, P4HA1, P4HB, RBM4, SART3, TNRC6A, TNRC6B, UPF1 and CC YBX1. Interacts with the P-body components DCP1A and XRN1. CC Associates with polysomes and messenger ribonucleoproteins CC (mNRPs). Interacts with RBM4; the interaction is modulated under CC stress-induced conditions, occurs under both cell proliferation CC and differentiation conditions and in an RNA- and phosphorylation- CC independent manner. Interacts with LIMD1, WTIP and AJUBA (By CC similarity). Interacts with TRIM71 (PubMed:19898466, CC PubMed:22508726, PubMed:22735451). Interacts with APOBEC3G in an CC RNA-dependent manner.
