NEW YORK (GenomeWeb) — A team of scientists from the Scripps Research Institute this week reported the crystal structure of a microRNA bound to human Argonaute 2 both before and after their engagement with a target mRNA, showing how the protein starts off by exposing only a small portion of its guide RNA as the complex searches for targets.

The research also identified a key aspect of how an miRNA/Ago2 complex uses a metal ion to prevent degradation of a target in the absence of extensive complementarity in favor of repressing its translation.
