== Function ==
===Crystal structure of the DGCR8 dimerization domain===
[https://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>
