Q: It regulates the expression of cis-Nat genes in Arabidopsis, and its failure is the cause of the FMR1 mutation in fragile X syndrome. Drosha and Pasha are proteins that disrupt exportin-mediated transport involved in this process, which leaves behind subcomponents that bind to foreign molecules and targets them for the RDE-1 nuclease. Dicer cuts out the stem and loop structure of the double strand precursor to create a single strand template used by the RISC complex to repress translation or destroy messenger templates. Earning a Nobel prize for Andrew Fire and Craig Mello, FTP name this naturally occurring gene silencing process also used by biologists to inhibit gene expression, often using micro RNA or siRNA.
