The γ subunit of the Na,K-ATPase is a small, single transmembrane protein (mass ≈ 7 kDa) expressed primarily in renal tissue, in approximately equimolar amounts compared with the α and β subunits ().It has substantial homology to CHIF (corticosteroid-induced factor) (), mat 8 (), and phospholemman (), which have similar trans-membrane organization (C terminus in, N terminus out) . Sodium/potassium-transporting ATPase subunit betainteracting protein 2 Add BLAST:
The sodium/potassium-transporting ATPase is composed of a catalytic alpha subunit, an auxiliary non-catalytic beta subunit and an additional regulatory subunit. Interacts with regulatory subunit FXYD1 (PubMed, PubMed, PubMed). Interacts with regulatory subunit FXYD3 (PubMed). Both Na +,K +-ATPase and H +,K +-ATPase belong to the family of P-type ATPases, which transport ions across the plasma membrane ().The Na +,K +-ATPase is found in almost all animal cells and is essential for the maintenance of cellular ion gradients, whereas the gastric H +,K +-ATPase is located in parietal cells of the gastric mucosa, where it is responsible for acid secretion by the .

The Na,K-ATPase consists of an α- and β-subunit. Moloney sarcoma virus-transformed MDCK cells (MSV-MDCK) express low levels of Na,K-ATPase β c expression of Na,K-ATPase β 1-subunit in these cells increased the protein levels of the α 1-subunit of Na, increase was not due to altered transcription of the α 1-subunit gene or half-life of the α 1-subunit protein.

Renal cortex Na+,K+-ATPase activity was higher in placebo-treated adults and newborns than fetuses. Cerebral cortex Na+,K+-ATPase activity was higher in dexamethasone- than placebo-treated adults, and α1-expression higher in fetuses of dexamethasone- than placebo-treated ewes at 60% and 80% by: 3.
The main finding of the present study is that mRNA levels of the Na +:K +:ATPase α 1-subunit in the renal cortex and outer and inner medulla did not change during modifications of salt intake or administration of the loop diuretic, furosemide, from 1 to 7 by: 3.

The Na,K‐ATPase is a ubiquitous cation pump of the plasma membrane that uses the energy of ATP hydrolysis to transport Na + ions out of and K + ions into the cell. The resulting Na + gradient provides the energy for the transport activity of other transporters involved in basic and specialized cellular functions (for review, see Horisberger, ).Cited by: 1.
Introduction. The Na + /K +-ATPase enzyme is a transmembrane heterodimer composed of two α-subunits (ca kDa) and two β-subunits (ca 40 kDa).The α-subunits are the catalytic components containing an intracellular ATP binding site, a phosphorylation site, and an extracellular site where ouabain, a highly specific inhibitor, binds (Skou and Esmann, ).Cited by: 5.
Na(+), K(+)-ATPase: the new face of an old player in pathogenesis and apoptotic/hybrid cell death Article Literature Review in Biochemical Pharmacology 66(8) November with 49 Reads. Na⁺/K⁺-ATPase is an enzyme found in the membrane of all animal cells.
It performs several functions in cell physiology. The Na+ /K+ -ATPase enzyme is active. For every ATP molecule that the pump uses, three sodium ions are exported and two potassium ions are imported; there is hence a net export of a single positive charge per pump cycle.
The sodium–potassium pump was discovered in by the BRENDA: BRENDA entry. It has been believed that inhibition of the Na,K-ATPase in cardiomyocytes raises cytoplasmic sodium levels, thereby inhibiting the sodium-calcium exchanger and raising cytoplasmic calcium levels, which is imagined to have a direct effect on the heart's contractility, but there is also evidence to suggest that digitalis strengthens the parasympathetic nervous system by Cited by: Na +/K -ATPase is an ion pump that translocates Na and K ions against the electrochemical gradients across the plasma membrane (Skou, ).
The enzyme is composed of a large catalytic subunit (α-subunit), a membrane-spanning auxiliary subunit (β-subunit) and a small regulatory subunit (γ-subunit).
