Substrate-dependent effects on the conformational equilibrium of the Na +, K +-ATPase monitored by VCF [PDF]

, 2009
The Na+,K+-ATPase was discovered more than 50 years ago, but even today the pumpcycle and its partial reactions are still not completely understood.

F-actin reorganization by V-ATPase inhibition in prostate cancer

Biology Open, 2017
The vacuolar ATPase (V-ATPase) proton pump sustains cellular pH homeostasis, and its inhibition triggers numerous stress responses. However, the cellular mechanisms involved remain largely elusive in cancer cells.

Na+, K+-ATPase and Ca2+-ATPase activities in the cochlear lateral wall following surgical induction of hydrops.

, 2011
Na+,K+-ATPase and Ca2+-ATPase activities have not been studied quantitatively in the cochlea affected by endolymphatic hydrops. The present study was designed to measure quantitatively the Na+,K+-ATPase and Ca2+-ATPase activities in the cochlear lateral ...

Control of calcium homeostasis in Schistosoma mansoni

Memorias do Instituto Oswaldo Cruz, 2001
Calcium signalling is fundamental for muscular contractility of Schistosoma mansoni. We have previously described the presence of transport ATPases (Na+,K+-ATPase and (Ca2+-Mg2+)-ATPase) and calcium channels (ryanodine receptors - RyR) involved in ...

A programmable optical angle clamp for rotary molecular motors [PDF]

, 2007
Optical tweezers are widely used for experimental investigation of linear molecular motors. The rates and force dependence of steps in the mechanochemical cycle of linear motors have been probed giving detailed insight into motor mechanisms. With similar

V-ATPase Dysfunction in the Brain: Genetic Insights and Therapeutic Opportunities

Cells
Vacuolar-type ATPase (v-ATPase) is a multimeric protein complex that regulates H+ transport across membranes and intra-cellular organelle acidification. Catabolic processes, such as endocytic degradation and autophagy, strictly rely on v-ATPase-dependent

The impact of 3-sulfo-taurolithocholic acid on ATPase activity in patients’ colorectal cancer and normal colon tissues, and its hepatic effects in rodents

Frontiers in Veterinary Science
Colorectal cancer is influenced by genetic mutations, lifestyle factors, and diet, particularly high fat intake, which raises bile acid levels in the intestinal lumen.

HCO3−-independent pH Regulation in Astrocytes in Situ Is Dominated by V-ATPase

, 2015
The mechanisms of HCO3−-independent intracellular pH (pHi) regulation were examined in fibrous astrocytes within isolated neonatal rat optic nerve (RON) and in cultured cortical astrocytes.

V-ATPase C Acts as a Receptor for Bacillus thuringiensis Cry2Ab and Enhances Cry2Ab Toxicity to Helicoverpa armigera

Insects
Cry2Ab is a significant alternative Bacillus thuringiensis (Bt) protein utilized for managing insect resistance to Cry1 toxins and broadening the insecticidal spectrum of crops containing two or more Bt genes. Unfortunately, the identified receptors fail
