Scientists have gotten their first detailed look at the molecular structure of an enzyme that Nature has been using for eons to help silence unwanted genetic messages. A team of researchers with ...

Researchers at the Center for RNA Research, Institute for Basic Science (IBS), in Seoul, have published a study with critical new insights into the structure and function of the Dicer enzyme. Dicer is ...

(SALT LAKE CITY)—Dicer, an enzyme essential for life, cleaves long double-stranded RNA (dsRNA) into short pieces that regulate gene expression. But in many ways dsRNA molecules all look alike, and ...

The first crystal structure of Dicer, an enzyme that initiates RNA interference (RNAi), suggests how it works. RNAi is a process in which short RNA molecules recognize messenger RNAs and mark them for ...

Researchers at University of Utah Health have discovered a protein that cuts apart the genetic material of harmful invading viruses. Their research shows how the protein detects the intruders and ...
