Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

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

FEBS 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 ...

Remarks on second-order quadratic systems in algebras

Electronic Journal of Differential Equations, 2017
This paper is an addendum to our earlier paper [8], where a systematic study of quadratic systems of second order ordinary differential equations defined in commutative algebras was presented.

Derivations, generalized derivations, and *-derivations of period 2 in rings

TURKISH JOURNAL OF MATHEMATICS, 2018
Summary: The aim of this article is to discuss the existence of certain kinds of derivations and \(^*\)-derivations that are of period 2. Moreover, we obtain the form of generalized reverse derivations and generalized left derivations of period 2.

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

FEBS 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.

Metrics for investigations into L2 knowledge of derivational affixes

Vocabulary Learning and Instruction
Knowledge of derivational affixes makes an important contribution to second language learners' success when reading. Yet while the effects of some learner variables (L2 proficiency, L1 background) have been investigated, there has been little research ...

Extending Derivations

Publications of the Research Institute for Mathematical Sciences, 1984
Let (\({\mathcal A},G,\tau)\) be a \(C^*\)-dynamical system, where G is a compact abelian group, \({\mathcal A}^{\tau}\) be the fixed point algebra, and \(\delta_ 0:{\mathcal D}_ 0\to {\mathcal A}^{\tau}\) be a \({}^*\)- derivation defined on a \({}^*\)-subalgebra \({\mathcal D}_ 0\) of \({\mathcal A}^{\tau}\).

Derivations and Alberti representations [PDF]

, 2013
We relate generalized Lebesgue decompositions of measures in terms of curve fragments (“Alberti representations”) and Weaver derivations. This correspondence leads to a geometric characterization of the local norm on the Weaver cotangent bundle of a ...

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

FEBS 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 ...

Notes on Semiprime Ideals with Symmetric Bi-Derivation

Axioms
In this paper, we prove many algebraic identities that include symmetric bi-derivation in rings which contain a semiprime ideal. We intend to generalize previous results obtained for semiprime rings with symmetric derivation using semiprime ideals in ...
