| Outline of Final Research Achievements |
MicroRNA (miRNA) is a small non-coding RNA molecule found in eukaryotes that functions in regulation of gene expression by binding to mRNA in a sequence-dependent manner and causing mRNA degradation and/or inhibition of translation. We analyzed molecular mechanism of miRNA precursor processing in the model plant Arabidopsis thaliana by using purified recombinant proteins expressed in insect cells. We gained insights into how efficient miRNA precursor processing is carried out by the RNaseIII family endoribonuclease Dicer-Like1 (DCL1) and its associated proteins.
