Kinase atlas uncovers hidden layers of cell signaling regulation
(MEMPHIS, Tenn. – November 6, 2025) The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme’s “tail” called phosphorylation patterns. Scientists at St. Jude Children’s Research Hospital explored these patterns, identifying 117 kinases that could phosphorylate multiple locations within the protein tail. This greatly expands upon the set of kinases previously known to phosphorylate RNA polymerase II. The work also links the enzyme’s activity to ...
