In terms of crystal structure, the first Dicer to be explored was that from the protozoan Giardia intestinalis. Thus, a novel mechanism for regulation of gene expression, the epigenetic silencing of genes by miRNAs, was discovered.

In the moss Physcomitrella patens DCL1b, one of four DICER proteins, is not involved in miRNA biogenesis but in dicing miRNA target transcripts. Дicer orthologs are present in many other organisms. Subsequent experiments testing RNase III family enzymes abilities to create RNA fragments narrowed the search to Drosophila CG4792, now named Dicer. This experiment showed that RISC was not responsible for generating the observable small nucleotide fragments. Dicer's ability to generate around 22 nucleotide RNA fragments was discovered by separating it from the RISC enzyme complex after initiating the RNAi pathway with dsRNA transfection. Bernstein sought to discover the enzyme responsible for generating small RNA fragments from double-stranded RNA.

5 Diagnostic and therapeutic applicationsДicer 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.

RISC has a catalytic component Argonaute, which is an endonuclease capable of degrading messenger RNA (mRNA). Dicer facilitates the activation of the RNA-induced silencing complex (RISC), which is essential for RNA interference. These fragments are approximately 20вЂ“25 base pairs long with a two-base overhang on the 3вЂІ-end. 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 interfering RNA and microRNA, respectively.
