New insights into the function of mammalian Argonaute2.

Uncovering the mechanisms that recognise a microRNA (miRNA) target is 1 of the biggest challenges because the Ago-miRNA complex is able to overcome different derogations of complementarity when binding targets. However, the recently solved crystallographic structure of Argonaute2 (Ago2) and a high-throughput analysis that used repurposed sequencing techniques has brought us closer to achieving this goal.
