  • Function

    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.
  • Tissue specificity

    Ubiquitously expressed.
  • Sequence similarities

    Contains 2 DRBM (double-stranded RNA-binding) domains.
    Contains 1 WW domain.
  • Domain

    Both DRBM domains are required for efficient binding to pri-miRNA. The region between residues 276 and 498 has an autoinhibitory function on pri-miRNA processing activity.
  • Cellular localization

    Nucleus. Nucleus > nucleolus. Colocalizes with nucleolin and DROSHA in the nucleolus. Mostly detected in the nucleolus as electron-dense granular patches around the fibrillar center (FC) and granular component (GC). Also detected in the nucleoplasm as small foci adjacent to splicing speckles near the chromatin structure. Localized with DROSHA in GW bodies (GWBs), also known as P-bodies.

Thank you for your reply.

I have sent you a vial of ab36865 as a free of charge replacement for ab90579 which was not working for you in western blotting. Your new order number for your records only is***.

If you experience any issues with the new vial of the antibody, or if there is anything else I can help you with, please let me know.

Thank you for contacting Abcam.

I am sorry about the issues you have been having with ab90579 in western blot. The antibody is covered under our Abpromise for six months and is guaranteed to work in western blot on human (but not mouse) samples.

Based on the information that you have provided, I do not think that any protocol tips that I could give would help resolve the issue, therefore I would be happy to replace or refund the antibody for you. Currently we only have the same lot of ab90579 in stock as you originally received, therefore it may be better to either receive a different DGCR8 antibody (possible another vial of ab36865), or any other that you are interested in. Or I could process a refund.

Please let me know how you would you like to continue and if you do wish to receive a replacement the catalogue number of that antibody.

I look forward to your reply and helping to resolve the issue.
