Two distinct mechanisms of RNA polymerase II elongation stimulation in vivo.

Molecules and Cells, 2021
Transcription by RNA polymerase II (RNA Pol II) relies on the elongation factors PAF1 complex (PAF), RTF1, and SPT6. Here, we use rapid factor depletion and multi-omics analysis to investigate how these elongation factors influence RNA Pol II elongation ...

The cytoskeleton, elongation and the control of elongation

Cell Biology International, 2003
The epidermis is often considered to be the growthlimiting cell layer in young, growing herbaceous plants (Niklas, 1992). In his classic work, Green (1980) elaborated this idea further for organ development, and attributed a crucial role to the orientation of cellulose fibrils as indicator of mechanical properties.

Elongation Factor P and the Control of Translation Elongation

Annual Review of Microbiology, 2017
Elongation factor P (EF-P) binds to ribosomes requiring assistance with the formation of oligo-prolines. In order for EF-P to associate with paused ribosomes, certain tRNAs with specific d-arm residues must be present in the peptidyl site, e.g., tRNAPro.

An Elongation- and Ligation-Based qPCR Amplification Method for the Radiolabeling-Free Detection of Locus-Specific N6 -Methyladenosine Modification.

Angewandte Chemie, 2018
The epitranscriptomic mark N6 -methyladenosine (m6 A) is the most abundant RNA modification in eukaryotic mRNA, but various limitations in currently available m6 A detection methods have precluded routine identification of m6 A marks at the single-site ...

ELONGATION AND ENCLOSURE

Perceptual and Motor Skills, 2005
Previous work suggested that elongation, horizontal area, and the boundary material might influence impressions of enclosure. This article describes an experiment in which these three factors were crossed. Ratings of open/enclosed by 15 respondents on 16 plazas indicated that the elongation ratio (range: 1:1 up to 1:1.8) had the ...

Translation Elongation

2014
The synthesis of proteins in eukaryotes is typically divided into four steps, i.e. initiation, elongation, termination and ribosome recycling. This key biological event is tightly regulated by the cell. Under condition of increased demand or reduced production of cellular energy the cell can downregulate this process.

The elongation of the mandible

American Journal of Orthodontics, 1967
A SATISFACTORY method for predicting mandibular elongation has not been reported, despite the importance of reliable predictions in orthodontic treatment. Apart from the difficulties of planning treatment without reliable forecasts of growth, the precise results of treatment procedures cannot be assessed reliably if the extent of the changes that would

Elongated styloid process: when is it really elongated?

Dentomaxillofacial Radiology, 2004
The styloid process (SP) is often denoted as elongated when it is longer than 30 mm or 33 mm. These dimensions, based on early reports, do not respect the natural variation of the SP. The aim of this study is to investigate the natural variation of the length of the SP.

Elongate Coarctation of the Aorta

Archives of Surgery, 1959
Four patients have undergone surgery for the treatment of elongate coarctation of the aorta during the past 10 years at either the Cook County or the Presbyterian Hospital of Chicago. We are presenting the salient features in these cases. Report of Cases Case 1.

Wasted by an elongation factor

Trends in Genetics, 1998
Some features of the wasted mouse phenotype are shared with the human autosomal recessive disorders ataxia–telangiectasia (AT) (caused by defects in the ATM gene) and Nijmegen breakage syndrome (NBS). These are immunodeficiency, ataxia, chromosomal instability and hypersensitivity of lymphocytes to ionizing radiation.
