Brain Na+, K+-ATPase activity In aging and disease
(Master Publishing Group, 2014-07)
Na+/K+ pump or sodium- and potassium-activated adenosine 5’-triphosphatase (Na+, K+-ATPase), its enzymatic version, is a crucial protein responsible for the electrochemical gradient across the cell membranes. It is an ion ...
Mechanisms of PKC-dependent Na+ K+ ATPase phosphorylation in the rat kidney with chronic renal failure
(Taylor & Francis, 2009-07)
The present work was designed to study Na+ K+ ATPase alpha1-subunit phosphorylation in rats with chronic renal failure (CRF) in comparison with normal rats. Na+ K+ ATPase alpha1-subunit phosphorylation degree was measured ...
The crustacean gill (Na(+),K(+))-ATPase: Allosteric modulation of high- and low-affinity ATP-binding sites by sodium and potassium
(ELSEVIER SCIENCE INC, 2008)
The blue crab, Callinectes danae, tolerates exposure to a wide salinity range employing mechanisms of compensatory ion uptake when in dilute media. Although the gill (Na(+), K(+))-ATPase is vital to hyperosmoregulatory ...
Atividade e estado de fosforilação da Na+,K+-ATPase nas convulsões induzidas por pentilenotetrazol em camundongos
(Universidade Federal de Santa MariaBrasilFarmacologiaUFSMPrograma de Pós-Graduação em FarmacologiaCentro de Ciências da Saúde, 2012-02-29)
In the brain, Na+,K+-ATPase activity is essential for maintaining of the electrochemical gradient
underlying the resting potential and release and uptake of neurotransmitters, and a decrease in its
activity alters brain ...
Alternative cycling modes of the Na+/K+-ATPase in the presence of either Na+ or Rb+
(Elsevier, 2013-05)
A comprehensive study of the interaction between Na+ and K+ with the Na+/K+-ATPase requires dissecting the incidence of alternative cycling modes on activity measurements in which one or both of these cations are absent. ...
Identification of a crab gill FXYD2 protein and regulation of crab microsomal Na, K-ATPase activity by mammalian FXYD2 peptide
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
This investigation discloses the recognition of an FXYD2 protein in a microsomal Na,K-ATPase preparation from the posterior gills of the blue crab, Callinectes danae, by a mammalian (rabbit) FXYD2 peptide specific antibody ...
Rb+ occlusion stabilized by vanadate in gastric H+/K+-ATPase at 25 ºC
(Elsevier Science, 2011-01)
Despite its similarity with the Na+/K+-ATPase, it has not been possible so far to isolate a K+-occluded state in the H+/K+-ATPase at room temperature. We report here results on the time course of formation of a state ...
Regulation by the exogenous polyamine spermidine of Na,K-ATPase activity from the gills of the euryhaline swimming crab Callinectes danae (Brachyura, Portunidae)
(ELSEVIER SCIENCE INC, 2008)
Euryhaline crustaceans rarely hyporegulates and employ the driving force of the Na,K-ATPase, located at the basal surface of the gill epithelium, to maintain their hemolymph osmolality within a range compatible with cell ...
