microRNAs bind Argonaute proteins, guiding silencing of target mRNAs. CLIP-seq has now been used to map microRNA targets bound by Ago2 in a Dicer-dependent fashion in mouse ES cells. The study reveals that certain sets of transcripts, such as TGF-β signaling pathway components, tend to be targeted, and also identifies a G-rich motif in targets that may modulate regulation.
