Diacylglycerol regulates the plasma membrane calcium pump from human erythrocytes by direct interaction
(Archives of Biochemistry and Biophysics, 2013)
The Effect of Ethanol on the Plasma Membrane Calcium Pump Is Isoform-specific
(THE JOURNAL OF BIOLOGICAL CHEMISTRY, 2017)
Expressão de proteínas envolvidas no transporte transepitelial de cálcio na próstata de ratos em envelhecimento
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE MORFOLOGIAPrograma de Pós-Graduação em Biologia CelularUFMG, 2020-02-19)
Calcium is a second messenger crucial for the execution of diverse cellular functions, including cell proliferation, survival and death. Its transport across epithelia is performed in three steps through the action of ...
Differential Effects of G- and F-Actin on the Plasma Membrane Calcium Pump Activity
(Humana Press, 2012-11)
We have previously shown that plasma membrane calcium ATPase (PMCA) pump activity is affected by the membrane protein concentration (Vanagas et al., Biochim Biophys Acta 1768:1641-1644, 2007). The results of this study ...
Expression of calcium-buffering proteins in rat intrinsic laryngeal muscles
(Wiley-Blackwell, 2015-06-01)
Intrinsic laryngeal muscles (ILM) are highly specialized muscles involved in phonation and airway protection, with unique properties that allow them to perform extremely rapid contractions and to escape from damage in ...
Selectivity of plasma membrane calcium ATPase (PMCA)-mediated extrusion of toxic divalent cations in vitro and in cultured cells
(Springer, 2017-07)
In the recent years, the toxicity of certain divalent cations has been associated with the alteration of intracellular Ca2+ homeostasis. Among other mechanisms, these cations may affect the functionality of certain ...
E2P-like states of plasma membrane Ca2+-ATPase characterization of vanadate and fluoride-stabilized phosphoenzyme analogues
(Elsevier Science, 2019-02)
The plasma membrane Ca2+‑ATPase (PMCA) belongs to the family of P-type ATPases, which share the formation of an acid-stable phosphorylated intermediate as part of their reaction cycle. The crystal structure of PMCA is ...
Thermal stability of the plasma membrane calcium pump: Quantitative analysis of its dependence on lipid-protein interactions
(Springer, 2000-02)
Thermal stability of plasma membrane Ca2+ pump was systematically studied in three micellar systems of different composition, and related with the interactions amphiphile-protein measured by fluorescence resonance energy ...
The role of the Ca2+ binding ligand Asn879 in the function of the plasma membrane Ca2+ pump
(Elsevier Science, 2009-12)
Asn879 in the transmembrane segment M6 of the plasma membrane Ca2+ pump (PMCA human isoform 4xb) has been proposed to coordinate Ca2+ at the transport site through its carboxylate. This idea agrees with the fact that this ...
