Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

On negation in yes/no questions in Serbo-Croatian

open access: yes, 2006
The phenomenon discussed in this paper is the so-called expletive negation in negated yes/no questions in Serbo-Croatian. The term expletive negation seems, at this point to be a useful descriptive term for the phenomenon in question. One of the goals of

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Children\u27s Understanding of the Semantics of Negation

open access: yes, 2010
The central focus of this project is to discover children’s understanding of the semantics, or meaning, of negation. Children’s knowledge of negation develops, in part, by directing attention away from a word to something else (i.e., contrast classes ...

Las ambigüidades de la negación: un análisis lógico-lingüístico [PDF]

open access: yesPrincípios, 2009
Cet article prétend présenter quelques idées qui permettent d´élaborer une comparaison théorique sur la négation chez les philosophes, les logiciens et les linguistes. Dans l´introduction, nous présentons quelques questions concernant la négation.

Corpora Annotated with Negation: An Overview

open access: yesComputational Linguistics, 2020
Negation is a universal linguistic phenomenon with a great qualitative impact on natural language processing applications. The availability of corpora annotated with negation is essential to training negation processing systems.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

open access: yesFEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

When negation is not negation

open access: yes, 2008
In this paper I will discuss the formation of different types of yes/no questions in Serbian (examples in (1)), focusing on the syntactically and semantically puzzling example (1d), which involves the negative auxiliary inversion.
