This chapter focuses on the membrane transport proteins that are the members of the calcium-transporting adenosine triphosphatase (ATPase) family. Members of this family are only found in yeasts. The chapter presents an overview of the physical and biological properties of the family, its distribution...
A thermodynamic cycle for catalysis of calcium transport by the sarcoplasmic reticulum ATPase is described, based on equilibrium constants for the microscopic steps of the reaction shown in Equation 1 under a single set of experimental (formula; see text) conditions (pH 7.0, 25 degrees C, 100 ...
Synonyms Plasma membrane Ca 2+ ATPase ; Plasma membrane Ca 2+ pump ; PMCA Historical Background The existence of a plasma membrane calcium-transporting ATPase (PMCA) that actively pumps Ca 2+ ions out of the cell was first demonstrated in erythrocyte (red blood cell) membranes by Schatzmann ...

(PLs), severalprotein kinases, and bydimerizationvia the calmodulin-binding domain. Interaction with calmodulin stimulates theVmaxof the Ca2+-ATPase and decreases itsKm(Ca2+) by about an order of magnitude (from ∼10−5to ∼10−6moll−1). The plasma membrane Ca2+-ATPase ...

Plasma membranes contain three Ca2+-transporting systems, a specific channel, a pumping ATPase, and a Na+-Ca2+ exchanger. The first system, which mediates the downhill influx of Ca2+ into cells, has been known since 1958, when Ca2+ action potentials, imp

In order to clarify the action mechanism of wilforine, the plasma membrane calcium transporting ATPase (PMCA) and inositol 1,4,5-trisphosphate receptor (IP 3 R) from M. separata were studied. Results showed that the open reading frame of MsIP 3 R and MsPMCA were 8118bp and 3438bp in...
