Application
ATPase is used to liberate inorganic phosphorus from ATP. ATPase, from porcine cerebral cortex, has been used in inhibition assays of Na/K-ATPase activity .
Actions biochimiques/physiologiques
This membrane enzyme hydrolyzes ATP to ADP and orthophosphate. The hydrolysis is coupled with the exchange of sodium and potassium ions across the plasma membrane. The enzyme is present in almost all tissues of higher organisms, but it is most abundant in the kidney where it reabsorbs sodium ions from the glomerular filtrate. Na+,K+-ATPase is affected by changes in intracellular calcium. It is also sensitive to ouabain and inhibited by vanadate, and (in vitro) by SPAI-1, a peptide isolated from porcine duodenum. It has been reported to be regulated by phosphorylation by protein kinase A (PKA). Bufalin, and other cardiotonic steroids, may inhibit Na+/K+-ATPase activity and induce the differentiation of HL60, U937, and ML1 cells .

G-protein-coupled receptors (GPCRs) are critically regulated by β-arrestins, which not only desensitize G-protein signalling but also initiate a G-protein-independent wave of signalling. A recent surge of structural data on a number of GPCRs, including the β2 adrenergic receptor (β2AR)-G-protein complex

The STIM1-ORAI1 pathway of store-operated Ca(2+) entry is an essential component of cellular Ca(2+) signalling. STIM1 senses depletion of intracellular Ca(2+) stores in response to physiological stimuli, and relocalizes within the endoplasmic reticulum to plasma-membrane-apposed junctions, where it recruits and
