Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Evolution of mitochondrial RNA editing sites and stop codon-lacking transcripts in angiosperms
Communications BiologyWhile the evolution of mitochondrial protein-coding genes in angiosperms has been extensively studied, the post-transcriptional RNA processing remains under-explored.

The FASEB Journal, 2019 Promoter‐proximal RNA Polymerase II pausing, which occurs within the first 100 nucleotides of a gene, refers to a property of the Polymerase II to halt transcription temporarily but remain transcriptionally competent. Knowledge of proximally paused Polymerase II dynamics is important for understanding the regulation of mRNA production.

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

A Genome-Scale Atlas Reveals Complex Interplay of Transcription and Translation in an Archaeon
mSystems, 2023 The scale of post-transcriptional regulation and the implications of its interplay with other forms of regulation in environmental acclimation are underexplored for organisms of the domain Archaea.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Mitochondrial atp9 genes from petaloid male-sterile and male-fertile carrots differ in their status of heteroplasmy, recombination involvement, post-transcriptional processing as well as accumulation of RNA and protein product [PDF]
Theoretical and Applied Genetics, 2014 Petaloid cytoplasmic male-sterile carrots exhibit overexpression of the mitochondrial atp9 genes which is associated with specific features in organization and expression of these sequences. In carrots, the Sp-cytoplasm causes transformation of stamens into petal-like organs, while plants carrying normal N-cytoplasm exhibit normal flower morphology ...

The role of histone modifications in transcription regulation upon DNA damage
FEBS Letters, EarlyView.This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Applications of Recombinant Dna Technology in Gastrointestinal Medicine and Hepatology: Basic Paradigms of Molecular Cell Biology. Part B: Eukaryotic Gene Transcription and Post-Transcripional Rna Processing [PDF]
Canadian Journal of Gastroenterology, 2000 The transcription of DNA into RNA is the primary level at which gene expression is controlled in eukaryotic cells. Eukaryotic gene transcription involves several different RNA polymerases that interact with a host of transcription factors to initiate transcription.
