Adenovirus VA RNA: An essential pro-viral non-coding RNA.
Atlanta, United States. In Virus Res, Jul 2015
Following transcription by cellular RNA polymerase III, VA RNAs saturate the nuclear export protein Exportin 5 (Exp5) and the cellular endoribonculease Dicer, interfering with pre-micro (mi)RNA export and miRNA biogenesis, respectively.
Mammalian 5'-capped microRNA precursors that generate a single microRNA.
New Haven, United States. In Cell, 2014
MicroRNAs (miRNAs) are short RNA gene regulators typically produced from primary transcripts that are cleaved by the nuclear microprocessor complex, with the resulting precursor miRNA hairpins exported by exportin 5 and processed by cytoplasmic Dicer to yield two (5p and 3p) miRNAs.
Selective nuclear export mechanism of small RNAs.
Ch'ŏngju, South Korea. In Curr Opin Struct Biol, 2011
Since the 2004 publication of the first exportin structure, Cse1p, the X-ray structures of exportin-5 complexed with pre-microRNA, exportin-t complexed with tRNA, and three CRM1-related structures have revealed the binding mechanism involved in specific cargo recognition.
