GONUTS is under stress! The website is currently experiencing long-wait times and frequent time-outs due to the record number of students, groups, and annotations related to CACAO this semester. We are currently working on increasing performance -- please accept our apologies for the technical difficulties.
You can help reduce stress on the server by:
- not reloading pages frequently - this just adds
- opening links in new windows (so you can read the old page)
Category:GO:0070877 ! microprocessor complex
name: microprocessor complex
namespace: cellular_component
def: "A protein complex that binds to heme and to pri-miRNAs, and is required for the formation of a pre-microRNA (pre-miRNA), the initial step of microRNA (miRNA) biogenesis. The complex is composed of the double-stranded-RNA-specific RNase Drosha (also called RNASEN) and the RNA-binding protein DGCR8 (heme-free or heme-bound forms). Within the complex, DGCR8 function as a molecular anchor necessary for the recognition of pri-miRNA at dsRNA-ssRNA junction and directs RNASEN/Drosha to cleave the 3' and 5' strands of a stem-loop to release hairpin-shaped pre-miRNAs."
