Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS 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 ...

Spanish vs. English mediated lectures: A contrastive approach to the use of evidential markers

open access: yesRevista de Lenguas para Fines Específicos, 2013
In the last ten years, Spanish universities have started to incorporate English as a means of instruction. As a consequence, many lecturers –who regularly use their mother tongue for their teaching activity– have adapted their syllabus contents into ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS 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 ...

Cross-linguistic variation in modality systems: The role of mood

open access: yesSemantics and Pragmatics, 2010
The St'át'imcets (Lillooet Salish) subjunctive mood appears in nine distinct environments, with a range of semantic effects, including weakening an imperative to a polite request, turning a question into an uncertainty statement, and creating an ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS 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 ...
