Knockdown of the Sodium/Potassium ATPase Subunit Beta 2 Reduces Egg Production in the Dengue Vector, Aedes aegypti

Insects, 2023
The Na+/K+ ATPase (NKA) is present in the cellular membrane of most eukaryotic cells. It utilizes energy released by ATP hydrolysis to pump sodium ions out of the cell and potassium ions into the cell, which establishes and controls ion gradients ...

Phosphorylation of the Na,K-ATPase alpha-subunit by protein kinase A and C in vitro and in intact cells. Identification of a novel motif for PKC-mediated phosphorylation.

Journal of Biological Chemistry, 1994
Na,K-ATPase is a potential target for regulatory phosphorylation by protein kinase A and C (PKA and PKC). To identify the phosphorylation sites, we have mutated the alpha 1-subunit of Bufo marinus in a highly conservative PKA and in 20 different PKC ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Digoxin attenuates LPS-induced acute lung injury in mice via NF-κB and HIF-1α inhibition

Biomolecules & Biomedicine
Acute lung injury (ALI), which can progress to the highly lethal acute respiratory distress syndrome (ARDS), remains a condition with limited pharmacological interventions, highlighting the urgent need for mechanism-informed repurposing strategies ...

Molecular cloning and analysis of zebrafish voltage-gated sodium channel beta subunit genes: implications for the evolution of electrical signaling in vertebrates

BMC Evolutionary Biology, 2007
Background Action potential generation in excitable cells such as myocytes and neurons critically depends on voltage-gated sodium channels. In mammals, sodium channels exist as macromolecular complexes that include a pore-forming alpha subunit and 1 or ...

GABA-A Alpha 2/3 but Not Alpha 1 Receptor Subunit Ligand Inhibits Harmaline and Pimozide-Induced Tremor in Rats

Biomolecules, 2023
Treatment of tremors, such as in essential tremor (ET) and Parkinson’s disease (PD) is mostly ineffective. Exact tremor pathomechanisms are unknown and relevant animal models are missing.

Structural insights into the basis and evolution of interactions in multi-subunit protein assemblies. tryptophan synthase and titin FNIII-repeats [PDF]

, 2008
Cellular processes benefit from evolutionary shaping when optimized protein-protein interactions result in enhanced functionality. In fact, most cellular proteins are tightly embedded into biological networks that function following a modularity ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Hypoxia Inducible Factor-1 Alpha as a Diagnostic Marker in Early Diabetic Nephropathy

Biomedical and Biotechnology Research Journal
Background: Research on the diagnostic utility of hypoxia-inducible factor-1 alpha (HIF-1α) as an indicator of diabetic kidney disease (DKD) in the Indian population is lacking.

Individual knock out of glycine receptor alpha subunits identifies a specific requirement of glra1 for motor function in zebrafish.

PLoS ONE, 2019
Glycine receptors (GlyRs) are ligand-gated chloride channels mediating inhibitory neurotransmission in the brain stem and spinal cord. They function as pentamers composed of alpha and beta subunits for which 5 genes have been identified in human (GLRA1 ...
