Lund E, Dahlberg JE (2006) Substrate selectivity of exportin 5 and Dicer in the biogenesis of microRNAs.
After its formation, the pre-miRNA is actively transported from the nucleus to the cytoplasm by the Ran-GTP-dependent transporter Exportin 5 (Exp 5) [15,16].
In the nucleus, miRNAs are transcribed as primary pri-miRNA transcripts, and then they are processed to shape the precursor pre-miRNA stem loop structure and then is transported to the cytoplasm by RanGTP and Exportin 5 where they are cleaved by the Dicer RNAase III endonuclease and produce mature miRNA (21-23 nt) (11).
