Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Species-specific responses to community density in an unproductive perennial plant community. [PDF]

PLoS ONE, 2014
Most studies of density dependent regulation in plants consider a single target species, but regulation may also occur at the level of the entire community.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Habitat filtering masks the detection of phylogenetic and functional density dependence on seedling survival across seasons in a subtropical forest, Southwestern China

Ecological Processes
Background Negative density dependence and habitat filtering are crucial mechanisms driving species coexistence and community assembly. However, empirical evidence regarding how habitat filtering interacts with density dependence remains limited ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Conspecific negative density dependence decreases with increasing species abundance

Ecosphere, 2015
Conspecific negative density dependence (CNDD) is often involved in explaining the maintenance of species diversity in forest communities given that it may suppress the common species. Recent studies, in contrast, suggested that CNDD had a stronger effect on rare species than on common species and thus shaped the current tree abundance pattern. However,

Spatial patterns reveal negative density dependence and habitat associations in tropical trees [PDF]

Ecology, 2011
Understanding how plant species coexist in tropical rainforests is one of the biggest challenges in community ecology. One prominent hypothesis suggests that rare species are at an advantage because trees have lower survival in areas of high conspecific density due to increased attack by natural enemies, a process known as negative density dependence ...

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Negative polarization of agglomerate particles with various densities

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2011
We study the negative polarization produced by agglomerate particles of various density. We found that all types of agglomerates studied reveal similar dependence of negative polarization minimum Pmin and its location αmin on particle size and refractive
