"Our work shows that the sodium pump
plays a particularly important role in this cell to help replenish or recharge this compartment with the right ions.
Also the pumps such as sodium pump
, boiler feed pump, condensate extraction pump etc are shown rotating.
Although considerable functional evidences indicate the existence of the second sodium pump
, and its associated [Na.sup.+]-ATPase (for revision to see 3) as a different mechanism to [Na.sup.+]/[K.sup.+] pump, and its associated [Na.sup.+]/[K.sup.+]-ATPase, the protein responsible for this transport mechanism has not been identified or isolated.
Researcher discover new function of cardiac sodium pump
. Available at: http://www.sciencedaily.com/releases/2007/01/070115100535.htm.
Endogenous cardiac glycosides: hormones using the sodium pump
as signal transduction.
The sodium pump
([Na.sup.+],[K.sup.+]-ATPase) is essential for maintaining specific ion gradients that, in turn, are used to drive active transport of organic substrates such as amino acids (Christensen et al., 1967).
In normal cells, the sodium pump
plays a critical role transporting potassium into the cell and sodium out of the cell.
Sex, digitalis and the sodium pump
. Mol Interventions 2003;3:68-72.
The sodium pump
consumes a large portion of the metabolic, energy (40%) in sea urchin larvae.
Webster recently identified the bacterium's sodium pump
as a protein pigment known as cytochrone-o.
When turned on, MR leads to the expression of a protein called epithelial sodium channel (ENaC) and an enzyme called the sodium pump
. Both of these substances promote the re-absorption of salt, which causes the body to retain fluid and results in high blood pressure.
Cardiac glycosides regulate the activity of the sodium pump
(Na,K-ATPase), and the a-subunit of Na,K-ATPase is a recognized functional receptor for these compounds (3-7).
Replacing the [H.sub.2]O in solutions with [D.sub.2]O slows many chemical and biological reactions including the squid axon action potential , ionic currents , and the sodium pump
The new findings implicated this channel in maintenance of the activity of the sodium pump
in the kidney, the major driver of salt reabsorption.
The receptor for digoxin and other cardiac glycosides is the sarcolemmal sodium pump
