html) to identify the evolutionarily conserved regions of Dicer1 Ribonuclease III enzyme among animals.
The primary miRNAs are cleaved by ribonuclease III Drosha and the double-stranded DNA binding protein Pasha/DGCR8 into a 70- to 100-nucleotide stem loop structure pre-miRNAs, which are exported to the cytoplasm by exportin 5/Ran GTP.
Subsequently, cleavage by a ribonuclease III called Drosha and the double-stranded DNA binding protein DGCR8/Pasha generates a hairpin-shaped premiRNA.
