Supplementary information

The DGCR8 protein also known as Pasha in some organisms serves an important role in the microRNA (miRNA) processing machinery. It has a molecular mass of approximately 90 kDa and shows expression ubiquitously but with higher levels in tissues with active cell division like the brain and lungs. DGCR8 acts as a partner in a complex with Drosha and together they initiate the microRNA maturation process by cleaving primary miRNA transcripts into precursor miRNA in the nucleus.
Biological function summary

DGCR8 partners with Drosha to form the Microprocessor complex an important player in miRNA biogenesis. This complex identifies and accurately processes primary transcripts into precursor miRNAs a step essential for proper gene regulation. DGCR8's role is critical for maintaining the normal cellular function enabling the precise control of miRNA production which in turn modulates gene expression post-transcriptionally. Aberrations in its function affect the regulation of genes involved in cell cycle differentiation and development.

Pathways

DGCR8 holds a significant influence on the RNA interference (RNAi) pathway interacting closely with Drosha to regulate miRNA synthesis. This pathway is fundamental for the regulation of genetic networks involved in cellular development and homeostasis. In the context of the miRNA processing pathway DGCR8 links to proteins like Dicer which further processes precursor miRNAs in the cytoplasm. Proper function of these pathways ensures the balanced expression of mRNAn important for healthy cellular activities.

DGCR8 misregulation is associated with the development of DiGeorge syndrome and certain cancers. Alterations in its function can lead to compromised miRNA maturation impacting genes that control cell growth and survival. In DiGeorge syndrome haploinsufficiency of DGCR8 may contribute to the associated developmental anomalies. In cancer altered DGCR8 expression can disrupt miRNA profiles interacting further with proteins such as Argonaute to influence the dysregulation of gene expression profiles commonly observed in tumorigenesis.

Target data

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 (PubMed : 26027739, PubMed : 26748718). 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 (PubMed : 15531877, PubMed : 15574589, PubMed : 15589161, PubMed : 16751099, PubMed : 16906129, PubMed : 16963499, PubMed : 17159994). Specifically recognizes and binds N6-methyladenosine (m6A)-containing pri-miRNAs, a modification required for pri-miRNAs processing (PubMed : 25799998). Involved in the silencing of embryonic stem cell self-renewal (By similarity). Also plays a role in DNA repair by promoting the recruitment of RNF168 to RNF8 and MDC1 at DNA double-strand breaks and subsequently the clearance of DNA breaks (PubMed : 34188037).
