Opposing effects of Na+ and K+ on the thermal stability of Na+,K+-ATPase
(American Chemical Society, 2012-03)
Folding and structural stability are key factors for the proper biological function of proteins. Na+,K+-ATPase is an integral membrane protein involved in the active transport of Na+ and K+ across the plasma membrane. In ...
Espermidina diminui a atividade da enzima Na+,K+-ATPase pela via de sinalização NMDA/NOS/GMPc/PKG em hipocampo de ratos
(Universidade Federal de Santa MariaBRBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica Toxicológica, 2011-12-02)
Spermidine (SPD) is an endogenous polyamine with polycationic structure present in the central nervous system of mammals. SPD regulates biological processes, such as Ca2+ influx by glutamatergic N-methyl-D-aspartate receptor ...
Response to environmental salinity of Na+-K+ATPase activity in individual gills of the euryhaline crab Cyrtograpsus angulatus
(Elsevier Science, 2002-07)
The occurrence, localization and response to environmental salinity changes of Na+-K+ATPase activity were studied in each of the individual gills 4-8 of the euryhaline crab Cyrtograpsus angulatus from Mar Chiquita coastal ...
Possible role of sulphatide in the K+-activated phosphatase activity
(1983)
A microsomal fraction rich in (Na+ + K+)-ATPase has been isolated from the outer medulla of pig kidney. (Mg2+ + K+)-activated ouabain-sensitive phosphatase activity was studied in this preparation treated with arylsulphatase, ...
High affinity receptors but not low affinity receptors for neurotensin are involved in neuronal Na/K-ATPase inhibition by the peptide
(Research Trends, 2013-07)
Neurotensin acts as a neuromodulator or as a neurotransmitter that binds to a group of receptors. Two of the receptors, namely NTS1 and NTS2, bind to neurotensin with high affinity and low affinity, respectively. Neurotensin ...
Effect of ethanol on regulation of (Na + K)-adenosine triphosphatase by aldosterone and dexamethasone in cultured renal papillary collecting duct cells
(2002)
Chronic ethanol exposure causes alterations in biologic
membranes of different cell types. (Na + K)–adenosine
triphosphatase (ATPase), a membrane-bound enzyme
inhibited by the acute presence of ethanol, increases
its ...
Transverse tubules from frog skeletal muscle. Purification and properties of vesicles sealed with the inside-out orientation
(1986)
Transverse tubule vesicles were isolated from frog skeletal muscle by a procedure initially described by Rosemblatt (J. Biol. Chem. 256, 8140-8148 (1981)) and later modified by Hidalgo (J. Biol. Chem. 258, 13937-13945 ...
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 ...
Neurotensin inhibits neuronal Na+, K+-ATPase activity through high affinity peptide receptor
