Repression of RNA polymerase by the archaeo-viral regulator ORF145/RIP.
Sheppard C, Blombach F, Belsom A, Schulz S, Daviter T, Smollett K, Mahieu E, Erdmann S, Tinnefeld P, Garrett R, Grohmann D, Rappsilber J, Werner F. Sheppard C, et al. Nat Commun. 2016 Nov 24;7:13595. doi: 10.1038/ncomms13595. Nat Commun. 2016. PMID: 27882920 Free PMC article.
Little is known about how archaeal viruses perturb the transcription machinery of their hosts. Here we provide the first example of an archaeo-viral transcription factor that directly targets the host RNA polymerase (RNAP) and efficiently represses its activity. ORF145 fro …
