Molecular mechanism of Gαi activation by non-GPCR proteins with a Gα-Binding and Activating motif [PDF]

, 2017
Heterotrimeric G proteins are quintessential signalling switches activated by nucleotide exchange on Gα. Although activation is predominantly carried out by G-protein-coupled receptors (GPCRs), non-receptor guanine-nucleotide exchange factors (GEFs) have

Transcriptomic signatures reveal systemic adaptations and immune modulation in response to training and competitive racing in horses

Equine Veterinary Journal, EarlyView.
Abstract Background The molecular mechanisms underlying adaptation to physical exertion and racing stress in horses remain incompletely understood. Peripheral blood transcriptomics offers a minimally invasive method to monitor systemic responses to exercise and identify biomarkers of adaptation or overload. Objectives To evaluate transcriptomic changes

Enhanced Mutant Compensates for Defects in Rhodopsin Phosphorylation in the Presence of Endogenous Arrestin-1

Frontiers in Molecular Neuroscience, 2018
We determined the effects of different expression levels of arrestin-1-3A mutant with enhanced binding to light-activated rhodopsin that is independent of phosphorylation.

Phosducin regulates the expression of transducin betagamma subunits in rod photoreceptors and does not contribute to phototransduction adaptation. [PDF]

, 2007
For over a decade, phosducin's interaction with the betagamma subunits of the G protein, transducin, has been thought to contribute to light adaptation by dynamically controlling the amount of transducin heterotrimer available for activation by ...

Efficacy of omega‐3 fatty acids as a functional food: a multifaceted approach to health reinforcement

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Omega‐3 fatty acids (omega‐3s) are polyunsaturated fatty acids linked with numerous health benefits. Omega‐3s exhibit multifaceted activities through various mechanisms. Eicosapentaenoic acid (EPA) alleviates oxidative stress by lowering reactive oxygen species and improving oxidative stress in brain tissues and acts against neurodegenerative ...

Rhodopsin 7–The unusual Rhodopsin in Drosophila [PDF]

PeerJ, 2016
Rhodopsins are the major photopigments in the fruit fly Drosophila melanogaster. Drosophila express six well-characterized Rhodopsins (Rh1–Rh6) with distinct absorption maxima and expression pattern.

Structural diversity of neuronal calcium sensor proteins and insights for activation of retinal guanylyl cyclase by GCAP1. [PDF]

, 2014
Neuronal calcium sensor (NCS) proteins, a sub-branch of the calmodulin superfamily, are expressed in the brain and retina where they transduce calcium signals and are genetically linked to degenerative diseases.

Deep Proteomic Profiles of the Antarctic Diatom Fragilariopsis Cylindrus Under Varying Iron and Manganese Conditions

PROTEOMICS, EarlyView.
ABSTRACT Fragilariopsis cylindrus is a key diatom in the Southern Ocean, where low iron and manganese availability constrain primary production and biogeochemical activity. The molecular mechanisms used by polar diatoms, including F. cylindrus, to cope with trace metal limitations remain largely unexplored.
