| [[http://www.uniprot.org/uniprot/RNC_HUMAN RNC_HUMAN]] Ribonuclease III double-stranded (ds) RNA-specific endoribonuclease that is involved in the initial step of microRNA (miRNA) biogenesis. Component of the microprocessor complex that is required to process primary miRNA transcripts (pri-miRNAs) to release precursor miRNA (pre-miRNA) in the nucleus. Within the microprocessor complex, DROSHA cleaves the 3' and 5' strands of a stem-loop in pri-miRNAs (processing center 11 bp from the dsRNA-ssRNA junction) to release hairpin-shaped pre-miRNAs that are subsequently cut by the cytoplasmic DICER to generate mature miRNAs. Involved also in pre-rRNA processing. Cleaves double-strand RNA and does not cleave single-strand RNA. Involved in the formation of GW bodies.<ref>PMID:10948199</ref> <ref>PMID:14508493</ref> <ref>PMID:15589161</ref> <ref>PMID:15574589</ref> <ref>PMID:15531877</ref> <ref>PMID:15565168</ref> <ref>PMID:16751099</ref> <ref>PMID:16906129</ref> <ref>PMID:17159994</ref> [[http://www.uniprot.org/uniprot/DGCR8_HUMAN DGCR8_HUMAN]] Component of the microprocessor complex that acts as a RNA- and heme-binding protein that is involved in the initial step of microRNA (miRNA) biogenesis. Component of the microprocessor complex that is required to process primary miRNA transcripts (pri-miRNAs) to release precursor miRNA (pre-miRNA) in the nucleus. Within the microprocessor complex, DGCR8 function as a molecular anchor necessary for the recognition of pri-miRNA at dsRNA-ssRNA junction and directs DROSHA to cleave 11 bp away form the junction to release hairpin-shaped pre-miRNAs that are subsequently cut by the cytoplasmic DICER to generate mature miRNAs. The heme-bound DGCR8 dimer binds pri-miRNAs as a cooperative trimer (of dimers) and is active in triggering pri-miRNA cleavage, whereas the heme-free DGCR8 monomer binds pri-miRNAs as a dimer and is much less active. Both double-stranded and single-stranded regions of a pri-miRNA are required for its binding. Involved in the silencing of embryonic stem cells self-renewal.<ref>PMID:15589161</ref> <ref>PMID:15574589</ref> <ref>PMID:15531877</ref> <ref>PMID:16751099</ref> <ref>PMID:16906129</ref> <ref>PMID:16963499</ref> <ref>PMID:17159994</ref> | | [https://www.uniprot.org/uniprot/RNC_HUMAN RNC_HUMAN] Ribonuclease III double-stranded (ds) RNA-specific endoribonuclease that is involved in the initial step of microRNA (miRNA) biogenesis.
