SK Burley… - Molecular Cell, 2011 - Elsevier Capping of eukaryotic pre-mRNAs proceeds via a sequential three-step process, involving (1) removal of the 5′ γ-phosphate group by an RNA triphosphatase (RTase), (2) addition of GMP to the 5′ β-phosphate by a GTP-dependent guanylyltransferase (GTase), and (3) ...
T Lenasi, BM Peterlin… - Journal of Biological Chemistry, 2011 - ASBMB Promoter-proximal pausing of RNAPII coincides with the formation of the cap structure at the 5′ end of pre-mRNA, which is bound by the cap-binding protein complex (CBC). Although the positive transcription elongation factor b (P-TEFb) stimulates the release of RNAPII from ... Related articles
[HTML] from nih.govC Chu, K Das, JR Tyminski… - Proceedings of the …, 2011 - National Acad Sciences The enzyme guanylyltransferase (GTase) plays a central role in the three-step catalytic process of adding an m7 GpppN cap cotranscriptionally to nascent mRNA (pre-mRNAs). The 5′-mRNA capping process is functionally and evolutionarily conserved from unicellular organisms ... Cited by 1 - Related articles - All 4 versions

The Cu thicknesses (t Cu ) ranged from 5 to 500 nm. For Ta/Cu, the intensity of the ... Related articles - Cached - All 3 versions
