The Structure of Human Argonaute-2 in Complex with miR-20a
Open accessAbstract
SUMMARY Argonaute proteins lie at the heart of the RNA-induced silencing complex (RISC), wherein they use small RNA guides to recognize targets. Initial insight into the architecture of Argonautes came from studies of prokaryotic proteins, revealing a crescent-shaped base made up of the amino-terminal, PAZ, middle, and PIWI domains. The recently reported crystal structure of human Argonaute-2 (hAgo2), the “slicer” in RNA interference, in complex with a mixed population of RNAs derived from insect cells provides insight into the architecture of a eukaryotic Argonaute protein with defined biochemical and biological functions. Here, we report the structure of human Ago2 bound to a physiologically relevant microRNA, microRNA-20a, at 2.2 Å resolution. The miRNA is anchored at both ends by the Mid and PAZ domains and makes several kinks and turns along the binding groove. Interestingly, miRNA binding confers remarkable stability on hAgo2, locking this otherwise flexible enzyme into a stable conformation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
