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 ...

Relative subgroup growth and subgroup distortion

Groups, Geometry, and Dynamics, 2015
We study the relative growth of finitely generated subgroups in finitely generated groups, and the corresponding distortion function of the embeddings. We explore which functions are equivalent to the relative growth functions and distortion functions of finitely generated subgroups. We also study the connections between these two asymptotic invariants

Isolation and Capability of Dark Septate Endophyte Against Mancozeb Fungicide

Jurnal Ilmu Pertanian Indonesia, 2020
Mancozeb is a group member of dithiocarbamat fungicides that most widely applied in the field. The use of mancozeb causes residues that have negative effects on agricultural production system and on agricultural environment. This research aimed to obtain

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

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

FEBS 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 ...

Relative growth and condition factor of the Finescale Triggerfish in the southeastern Gulf of California

California Fish and Wildlife Journal
Relative growth and body condition of the Finescale Triggerfish (Balistes polylepis) were evaluated using fishery-dependent data from the southeastern Gulf of California across eight sampling periods between 2002 and 2024.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Rate of Relative Growth of Orthogonal Polynomials

Journal of Mathematical Analysis and Applications, 1993
Suppose \(p_ n(x)\) \((n=0,1,2,\dots)\) is a sequence of polynomials in the variable \(x\) defined by the recurrence \[ xp_ n(x)=a_{n+1}p_{n+1}(x)+b_ np_ n(x)+a_ np_{n-1}(x), \] with \(p_ 0\) a positive constant and \(p_{-1}=0\). A uniform upper bound is obtained for \[ {| p_ n(x)|^ p\over\sum_{k=0}^ n| p_ k(x)|^ p} \] for \(x\in[b-a,b+a]\) in case the
