Structural visualization of key steps in human transcription initiation. [PDF]
, 2013 Eukaryotic transcription initiation requires the assembly of general transcription factors into a pre-initiation complex that ensures the accurate loading of RNA polymerase II (Pol II) at the transcription start site. The molecular mechanism and function

Quantification bias caused by plasmid DNA conformation in quantitative real-time PCR assay. [PDF]
PLoS ONE, 2011 Quantitative real-time PCR (qPCR) is the gold standard for the quantification of specific nucleic acid sequences. However, a serious concern has been revealed in a recent report: supercoiled plasmid standards cause significant over-estimation in qPCR ...

Highly Improved Electrospray Ionization-Mass Spectrometry Detection of G-Quadruplex-Folded Oligonucleotides and Their Complexes with Small Molecules [PDF]
, 2017 G-quadruplexes are nucleic acids structures stabilized by physiological concentration of potassium ions. Because low stability G-quadruplexes are hardly detectable by mass spectrometry, we optimized solvent conditions: isopropanol in a triethylamine ...

High intrinsic hydrolytic activity of cyanobacterial RNA polymerase compensates for the absence of transcription proofreading factors [PDF]
, 2020 The vast majority of organisms possess transcription elongation factors, the functionally similar bacterial Gre and eukaryotic/archaeal TFIIS/TFS. Their main cellular functions are to proofread errors of transcription and to restart elongation via ...

Conformational classification of functional nucleic acids [PDF]
Nucleic Acids Symposium Series, 1999 The kink parameters would provide the tolerant aspect for irregular helical structure of nucleic acid. Using these kink parameters, the classification of conformation space was carried for the functional nucleic acid molecules. The kink parameters could afford us the simple structural aspects about the constructive parts of functional molecules.

Protein-DNA interactions: statistical analysis of interatomic contacts in major and minor grooves
Вавиловский журнал генетики и селекции, 2018 The interactions between protein and DNA in essence underlie all processes in a living cell. Understanding the principles of specific recognition of DNA sites will open the way to understand how these processes are controlled and to interfere in their ...
