General description

DGCR8 (DGCR8 microprocessor complex subunit) is a double-stranded RNA-binding protein mapped to the chromosome 22q11.2. It is composed of a WW domain and two double-stranded RNA-binding domains (dsRBDs).
DGCR8 contains an N-terminal region which is critical for nuclear localization and C-terminus which can directly and stably interact with the pri-mRNAs.

Application

Anti-DGCR8 (N-terminal) antibody produced in rabbit has been used in western blotting.
Anti-DGCR8 (N-terminal) antibody produced in rabbit has been used in:
  • western blotting
  • immunoprecipitation
  • immunofluorescence

Anti-DGCR8 (N-terminal) antibody produced in rabbit is suitable for immunoprecipitation (2.5-5μg using lysates of HEK-293T cells over expressing human DGCR8), indirect immunofluorescence (2-5μg/mL using paraformaldehyde fixed HEK-293T cells over expressing human DGCR8) and western blot at a dilution of 1-2μg/mL (using lysates of HEK-293T cells over expressing human DGCR8).

Biochem/physiol Actions

DGCR8 (DGCR8 microprocessor complex subunit) participates in the biogenesis of microRNA (miRNA, miR) as a major component of the microprocessor complex. DGCR8 provides guidance to the RNase III enzyme, Drosha during rRNA processing. It forms the microprocessor complex by binding to the RNase III enzyme Drosha, which further converts long primary miRNAs (pri-miRNAs) into short hairpins called precursor miRNAs (pre-miRNAs). The processed hairpins finally are transported to the cytoplasm for further processing by Dicer into mature miRNAs. DGCR8 is also required for global gene regulation and silencing of embryonic stem cell self-renewal. Deletion of DGCR8 chromosomal location has been reported in the DiGeorge and velocardiofacial syndrome.
DGCR8, also known as DiGeorge syndrome critical region 8, DGCRK8 is the cofactor that interacts with drosha and forms a functional complex called the ‘‘Microprocessor” which is essential for microRNA (miRNA) maturation. DGCR8 contains an N-terminal region which is critical for nuclear localization and the C-terminal region stably interacts with the pri-miRNAs.

Regulation of microRNA (miR) biogenesis is complex and stringently controlled. Here, we identify the kinase GSK3β as an important modulator of miR biogenesis at Microprocessor level. Repression of GSK3β activity reduces Drosha activity toward pri-miRs, leading to accumulation of unprocessed
