Fundamental mechanism discovered that fine-tunes gene expression & is disrupted in cancer
Credit: The Wistar Institute PHILADELPHIA and MELBOURNE, Australia -- (May. 17, 2021) -- A team of scientists from The Wistar Institute in Philadelphia and the Peter MacCallum Cancer Center in Melbourne, Australia, discovered a new checkpoint mechanism that fine-tunes gene transcription. As reported in a study published in Cell, a component of the Integrator protein complex tethers the protein phosphatase 2A (PP2A) to the site of transcription allowing it to stop the activity of the RNA polyme...
