Structure and Roles of V-type ATPases

T Vasanthakumar, JL Rubinstein - Trends in biochemical sciences, 2020 - cell.com
V-ATPases are membrane-embedded protein complexes that function as ATP hydrolysis-driven
proton pumps. V-ATPases are the primary source of organellar acidification in all …

Coordinated conformational changes in the V1 complex during V-ATPase reversible dissociation

T Vasanthakumar, KA Keon, SA Bueler… - Nature Structural & …, 2022 - nature.com
Vacuolar-type ATPases (V-ATPases) are rotary enzymes that acidify intracellular compartments
in eukaryotic cells. These multi-subunit complexes consist of a cytoplasmic V 1 region …

Structural comparison of the vacuolar and Golgi V-ATPases from Saccharomyces cerevisiae

T Vasanthakumar, SA Bueler, D Wu… - Proceedings of the …, 2019 - National Acad Sciences
Proton-translocating vacuolar-type ATPases (V-ATPases) are necessary for numerous
processes in eukaryotic cells, including receptor-mediated endocytosis, protein maturation, and …

[HTML][HTML] Ras-mutant cancers are sensitive to small molecule inhibition of V-type ATPases in mice

…, CR Liem, AJ de Smith, T Vasanthakumar… - Nature …, 2022 - nature.com
Mutations in Ras family proteins are implicated in 33% of human cancers, but direct
pharmacological inhibition of Ras mutants remains challenging. As an alternative to direct inhibition, …

Structural Insight into V-ATPase Regulation

Ras an intensely pursued target in drug discovery. As an alternative to direct …

[BOOK][B] Low Temperature Tolerance of Adult Drosophila Suzukii (Diptera: Drosophilidae)

R Jakobs - 2014 - search.proquest.com
The crop pest Drosophila suzukii, native to Southeast Asia, has been found in Ontario since
2010. This raises concern with respect to it establishing permanent populations, however, …

Recruitment and Mechanism of the Bacterial Type IV Pilus Motors

MCK McCallum - 2019 - search.proquest.com
The type IVa pilus system can be used for adhesion, natural competence, phage adsorption,
folded-protein secretion, surface sensing, and surface associated motility. Likewise, it is a …

SC Bickers, S Benlekbir… - Proceedings of the …, 2021 - National Acad Sciences
… We thank Stephanie Bueler with assistance in generating the ySCB1 yeast strain and
Thamiya Vasanthakumar and Zev Ripstein for helpful discussions regarding ATPase assays and …

Adult plasticity of cold tolerance in a continental-temperate population of Drosophila suzukii

R Jakobs, TD Gariepy, BJ Sinclair - Journal of insect physiology, 2015 - Elsevier
Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is a worldwide emerging pest of
soft fruits, but its cold tolerance has not been thoroughly explored. We determined the cold …
