Sodium and potassium ions are closely coupled with membrane ATPase which undergoes phosphorylation and dephosphorylation, thereby providing energy for transport of these ions against concentration gradients. (childrensmercy.org)
A family of plasma membrane exchange glycoprotein antiporters that transport sodium ions and protons across lipid bilayers. (nih.gov)
Membrane proteins that allow the exchange of hydrogen ions for potassium ions across the cellular membrane. (bvsalud.org)
Exchanger1
The sodium-hydrogen antiporter or sodium-proton exchanger (Na+/H+ exchanger) is a membrane protein that transports Na+ into the cell, and H+ out of the cell (antiport). (wikipedia.org)
Protons2
They are ANTIPORTERS that exchange vesicular PROTONS for cytoplasmic NEUROTRANSMITTER and play an essential role in regulating neurotransmission. (uams.edu)
Proton pump releases more protons into the stomach, thereby increasing the secretion of acid. (drugbank.com)
Exchangers1
Sodium-hydrogen exchangers (Na + /H + exchangers, NHE) are ATP-independent membrane glycoprotein transporters that are involved in the regulation of intracellular pH, cell volume and the cellular response to hormones and mitogens. (tocris.com)
In one study, transgenic mice over expressing this membrane protein were shown to have increased reabsorption and retention of sodium after increased salt intake. (wikipedia.org)
The transporters mediate the simultaneous efflux of a hydrogen ion and the influx of a sodium ion across the plasma membrane, the driving force being the inwardly directed electrochemical Na + gradient. (tocris.com)
The proton pump activity of dR achieves a maximum effect by green light when dR is expressed in the Escherichia coli ( E. Coli ) membrane 8 . (nature.com)
Upon release, histamine acts on H 2 receptors expressed on the basolateral membrane of parietal cells, leading to increased intracellular cAMP levels and activated proton pumps on parietal cells. (drugbank.com)
CPA21
H + antiporters of the CPA2 family (TC #2.A.37) to establish homology (K. Studley and M.H. Saier, Jr., unpublished results). (tcdb.org)
Subunit1
The enzyme transfers CO 2 from glutaconyl-CoA to a biotin carrier protein (the γ-subunit) that is subsequently decarboxylated by the carboxybiotin decarboxylation site within the Na + pumping beta subunit (Gcdβ). (tcdb.org)

1997). Sequence of a gene cluster from Malonomonas rubra encoding components of the malonate decarboxylase Na + pump and evidence for their function. (tcdb.org)
Loss of tubular function prevents the kidneys from excreting hydrogencations (H + ) and thereby causes metabolic acidosis. (medscape.com)
Loss of tubular function prevents the kidneys from excreting hydrogencations (H+) and thereby causes metabolic acidosis. (medscape.com)
Water1
Prospective studies involving very low birth weight (VLBW) infants (BW ≤1500 g) and extremely low birth weight (ELBW) infants (BW ≤1000 g) demonstrated a consistent pattern of fluid and sodium balance despite varying intakes of sodium and water over the first five to seven days of life [ 3,4 ].
