Circadian regulation of gene expression: at the crossroads of transcriptional and post-transcriptional regulatory networks
(Current Biology Ltd, 2014-08)
Gene expression programs activated in response to, or in anticipation of, environmental changes involve sequential steps, from transcription and RNA processing to nuclear export and translation. Here we review recent ...
Beyond transcription: Fine-tuning of circadian timekeeping by post-transcriptional regulation
(MDPI, 2018-12)
The circadian clock is an important endogenous timekeeper, helping plants to prepare for the periodic changes of light and darkness in their environment. The clockwork of this molecular timer is made up of clock proteins ...
Exploring in silico transcriptional and post-transcriptional gene regulatory networks in the Corynebacterium genus
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE BIOLOGIA GERALPrograma de Pós-Graduação em BioinformaticaUFMG, 2021-05-27)
Transcriptional and post-transcriptional regulation of gene expression are considered key regulatory steps in bacteria. Regulatory molecules such as transcription factors (TF), sigma-factors and small RNAs (sRNAs) modulate ...
Transcriptional and post-transcriptional control of the plant circadian gene regulatory network
(Elsevier Science, 2016-07-10)
The circadian clock drives rhythms in multiple physiological processes allowing plants to anticipate and adjust to periodic changes in environmental conditions. These physiological rhythms are associated with robust ...
Transcription initiation mapping in 31 bovine tissues reveals complex promoter activity, pervasive transcription, and tissue-specific promoter usage
(Cold Spring Harbor Laboratory Press, 2021-04)
Characterizing transcription start sites is essential for understanding the regulatory mechanisms that control gene expression. Recently, a new bovine genome assembly (ARS-UCD1.2) with high continuity, accuracy, and ...
Transcription rate modulation through the Trypanosoma cruzi life cycle occurs in parallel with changes in nuclear organisation
(Elsevier B.V., 2001-01-15)
In trypanosomes transcription occurs as large polycistronic units, with trans-splicing and polyadenylation generating each individual mRNA. There are no defined RNA. polymerase II promoters and mRNA stabilisation is most ...
A Genome-wide Screen for Neurospora crassa Transcription Factors Regulating Glycogen Metabolism
(Amer Soc Biochemistry Molecular Biology Inc, 2011-11-01)
Transcription factors play a key role in transcription regulation as they recognize and directly bind to defined sites in promoter regions of target genes, and thus modulate differential expression. The overall process is ...
Salicylic acid and reactive oxygen species interplay in the transcriptional control of defense genes expression
(2015)
It is well established that salicylic acid (SA) plays a critical role in the transcriptional reprograming that occurs during the plant defense response against biotic and abiotic stress. In the course of the defense response, ...
Light Regulates Plant Alternative Splicing through the Control of Transcriptional Elongation
(Cell Press, 2019-03)
Light makes carbon fixation possible, allowing plant and animal life on Earth. We have previously shown that light regulates alternative splicing in plants. Light initiates a chloroplast retrograde signaling that regulates ...
Zebrafish cnbp Intron1 Plays a Fundamental Role in Controlling Spatiotemporal Gene Expression During Embryonic Development
(WILEY-LISS, DIV JOHN WILEY & SONS INC, 2009-09-02)
Cellular nucleic acid binding protein (CNBP) is a strikingly conserved zinc-finger nucleic acid chaperone required for forebrain development.
Its depletion causes forebrain truncation mainly as a consequence of a reduction ...
