This protein is located in 5 target(s):

TargetCategoryDefinition
nucleoplasmcellular componentThat part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653]
cytoplasmcellular componentThe contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. [ISBN:0198547684]

Active In

This protein is active in 2 target(s):

TargetCategoryDefinition
nucleuscellular componentA membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. [GOC:go_curators]
cytoplasmcellular componentThe contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. [ISBN:0198547684]

Part Of

This protein is part of 2 target(s):

TargetCategoryDefinition
RISC-loading complexcellular componentA 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. [GOC:ab, GOC:BHF, GOC:nc, GOC:rph, PMID:18178619, PMID:19820710]
RISC complexcellular componentA ribonucleoprotein complex that contains members of the Argonaute family of proteins, small interfering RNAs (siRNAs) or microRNAs (miRNAs), and miRNA or siRNA-complementary mRNAs, in addition to a number of accessory factors. The RISC complex is involved in posttranscriptional repression of gene expression through downregulation of translation or induction of mRNA degradation. [PMID:10749213, PMID:15145345]

miRNA processingbiological processA 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.
