title: Pumilio turns on microRNA function.
abstract: Pumilio proteins PUM1 and PUM2 are shown to regulate microRNA-dependent gene silencing by induction of a conformational switch in the 3' untranslated region of p27 mRNA. This conformational change is required for efficient microRNA-mediated repression of this cell-cycle regulator in rapidly proliferating cells.
