Dicer, also known as endoribonuclease Dicer or helicase with RNase motif, is an enzyme that in humans is encoded by the DICER1 gene. Being part of the RNase III family, Dicer cleaves double-stranded RNA (dsRNA) and pre-microRNA (pre-miRNA) into short double-stranded RNA fragments called small … See more Dicer was given its name in 2001 by Stony Brook PhD student Emily Bernstein while conducting research in Gregory Hannon's lab at Cold Spring Harbor Laboratory. Bernstein sought to discover the enzyme responsible for … See more Human dicer (also known as hsDicer or DICER1) is classified a Ribonuclease III because it cleaves double-stranded RNA. In addition to two … See more Macular degeneration Age related macular degeneration is a prominent cause of blindness in developed countries. Dicer's role in this disease became apparent after it was discovered that affected patients showed decreased levels of Dicer in their See more Plant genomes encode for dicer like proteins with similar functions and protein domains as animal and insect dicer. For example, in the model organism Arabidopsis thaliana, … See more Micro RNA RNA interference is a process where the breakdown of RNA molecules into miRNA inhibits gene expression of specific host mRNA sequences. miRNA is produced within the cell starting from primary miRNA (pri-miRNA) in the See more Dicer can be used to identify whether tumors are present within the body based on the expression level of the enzyme. A study showed that many patients that had cancer had decreased expression levels of Dicer. The same study showed that lower Dicer expression … See more • gene expression • RISC • RNA interference • microRNA See more WebStructural basis for Dicer-like function of EcEEQ. The first glimpse at the RNase III active site was provided by our structure of A. aeolicus RIIID dimer 33 years after the discovery of the enzyme [Citation 17, Citation 18].
