The production of ribosomes plays a central role in regulating cell cycle progression and cancer proliferation. A new study by Gaviraghi et al ([Gaviraghi M, 2018]) shows that mRNA decapping coactivator PNRC 1 acts as a tumor suppressor by regulating ribosome biogenesis. PNRC 1 relocalizes the Dcp1/Dcp2 mRNA decapping complex to the nucleolus and promotes decapping of specific sno RNA s to disrupt the processing of ribosomal RNA . By slowing rRNA processing, and thus ribosome biogenesis, PNRC 1 acts as a gatekeeper that restrains oncogenic potential.
