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 ...
Circadian rhythms and post-transcriptional regulation in higher plants
(Frontiers, 2015-06-12)
The circadian clock of plants allows them to cope with daily changes in their environment. This is accomplished by the rhythmic regulation of gene expression, in a process that involves many regulatory steps. One of the ...
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 ...
Multiple mechanisms of growth hormone-regulated gene transcription
(Elsevier, 2007)
Diverse physiological actions of growth hormone (GH) are mediated by changes in gene transcription. Transcription can be regulated at several levels, including post-translational modification of transcription factors, and ...
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 ...
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 ...
Neighboring gene regulation by antisense long Non-Coding RNAs
(2015)
Antisense transcription, considered until recently as transcriptional noise, is a very common phenomenon in human and eukaryotic transcriptomes, operating in two ways based on whether the antisense RNA acts in cis or in ...
