abstract：:The function of protein phosphatase 1 nuclear-targeting subunit (PNUTS)--one of the most abundant nuclear-targeting subunits of protein phosphatase 1 (PP1c)--remains largely uncharacterized. We show that PNUTS depletion by small interfering RNA activates a G2 checkpoint in unperturbed cells and prolongs G2 checkpoint ...

We show that in plants, those introns, when located 3' of the stemloop, can promote mature miRNA accumulation, through a mechanism that likely operates at the level of miRNA processing or s...
