G protein beta gamma subunits synthesized in Sf9 cells. Functional characterization and the significance of prenylation of gamma [PDF]

, 1992
Heterotrimeric guanine nucleotide-binding regulatory proteins (G proteins) consist of a nucleotide-binding alpha subunit and a high- affinity complex of beta and gamma subunits.

Spatial Factors Play a Major Role as Determinants of Endemic Ground Beetle Beta Diversity of Madeira Island Laurisilva [PDF]

, 2013
The development in recent years of new beta diversity analytical approaches highlighted valuable information on the different processes structuring ecological communities.

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.

Climate and geographic distance are more influential than rivers on the beta diversity of passerine birds in Amazonia

Ecography, 2020
Variation in the spatial structure of communities in terms of species composition (beta diversity) is affected by different ecological processes, such as environmental filtering and dispersal limitation.

Elevation-dependent drivers of plant diversity across spatial scales on the Qinghai-Tibet Plateau

Frontiers in Ecology and Evolution
IntroductionIn mountain ecosystems, plant diversity often exhibits regular patterns along elevational gradients. Yet, it remains poorly understood how multiple factors jointly shape these patterns.MethodsTo fill this gap, we used a dataset of 758 ...

Potent in vitro and in vivo antifungal activity of a small molecule host defense peptide mimic through a membrane-active mechanism

Scientific Reports, 2017
Lethal systemic fungal infections of Candida species are increasingly common, especially in immune compromised patients. By in vitro screening of small molecule mimics of naturally occurring host defense peptides (HDP), we have identified several active ...

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 ...

Temporal beta diversity of lake plants is determined by concomitant changes in environmental factors across decades

Journal of Ecology, 2020
To comprehensively understand the impact of anthropogenic activities on biodiversity, we must understand how biodiversity has changed over time and what are the underlying processes.

Native diversity contributes to composition heterogeneity of exotic floras

Ecosphere, 2023
Variation in species composition among sites (beta diversity) is generally thought to be driven by environmental filtering and dispersal limitation, but the role of biotic interactions has not been sufficiently addressed.

Spatial Scaling in Model Plant Communities

, 2005
We present an analytically tractable variant of the voter model that provides a quantitatively accurate description of beta-diversity (two-point correlation function) in two tropical forests.
