GO:0035279 | miRNA-mediated gene silencing by mRNA destabilization | biological_process | An RNA interference pathway in which microRNAs (miRNAs) direct the cleavage of target mRNAs. Once incorporated into a RNA-induced silencing complex (RISC), a miRNA base pairing with near-perfect complementarity to the target mRNA will typically direct targeted endonucleolytic cleavage of the mRNA. Many plant miRNAs downregulate gene expression through this mechanism. [GOC:dph, GOC:mtg_lung, PMID:14744438, PMID:15196554, PMID:21118121, PMID:23209154] |
GO:0090625 | siRNA-mediated gene silencing by mRNA destabilization | biological_process | An siRNA-mediated post-transcriptional gene silencing pathway in which small interfering RNAs (siRNAs) direct the cleavage of target mRNAs. Once incorporated into a RNA-induced silencing complex (RISC), an siRNA will typically direct cleavage by base pairing with perfect or near-perfect complementarity to the target mRNA.

GO:0035196 | miRNA processing | biological_process | A process leading to the generation of a functional miRNA. Includes the cleavage of stem-loop RNA precursors into microRNAs (miRNAs). miRNAs are a class of small RNAs that primarily silence genes by blocking the translation of mRNA transcripts into protein, or by increasing the degradation of non-protein-coding RNA transcripts.

GO:0035278 | miRNA-mediated gene silencing by inhibition of translation | biological_process | An RNA interference pathway in which microRNAs (miRNAs) block the translation of target mRNAs into proteins. Once incorporated into a RNA-induced silencing complex (RISC), a miRNA will typically mediate repression of translation if the miRNA imperfectly base-pairs with the 3' untranslated regions of target mRNAs. [PMID:14744438, PMID:15196554] |
GO:0070922 | RISC complex assembly | biological_process | The process in which a single-stranded small RNA is incorporated within the RNA-initiated silencing complex (RISC). The assembly includes the maturation of the small RNA, the stabilization of the complex by accessory proteins of the RISC complex, duplex separation and the release of the second strand, forming a base-pairing completent complex that mediates gene silencing by small RNA.

The RISC complex is involved in posttranscriptional repression of gene expression through downregulation of translation or induction of mRNA degradation. [PMID:10749213, PMID:15145345] |
GO:0070578 | RISC-loading complex | cellular_component | A trimeric protein complex required for the formation of a mature RNA-induced silencing complex (RISC). In humans the complex is composed of the endonuclease Dicer (DICER1), TRBP (TARBP2) and the Argonaute protein Ago2 (EIF2C2/AGO2). Within the complex, Dicer and TRBP 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 Dicer and TRBP. This complex has endoribonuclease activity.
