In mixed platelet membrane vesicles the presence of two distinct endoplasmic reticulum-type calcium pump enzymes of 100 and 97 kD molecular mass has been demonstrated. We have previously shown that both calcium pumps were recognized by polyclonal ant

To maintain very low intracellular free Ca2+ concentration is essential for all eukaryotic cells. The P-type ATPase, responsible for the active transport of Ca2+ through the plasma membrane (PMCA) has been studied and characterized in red blood cells

Jurkat and MOLT-4 cultured T lymphoblasts were loaded with low concentrations (30–50 μm) of indo-1 and with high concentrations (3.5–4.5mm) of quin-2, respectively, in order to follow the activation of calcium transport pathways after stimulatio

The relationship between thrombin-evoked changes in intracellular calcium concentration ([Ca2+]i) and aggregation was examined in Indo-1-loaded human platelets. The stimulus-induced intracellular calcium release and external calcium influx, as well a

In inside-out red cell membrane vesicles trypsin digestion reduces the molecular mass of the 32P-labeled acyl-phosphate intermediate of the calcium pump from the original 140 kDa to about 80 kDa with a simultaneous activation of the calcium uptake. T

The characteristics of the calcium pump were investigated in intact human peripheral blood lymphocytes /PBL/ and in inside-out vesicles prepared from their plasma membranes. Intact PBL were loaded with calcium by a short exposure to A23187 ionophore.

In inside-out human red cell membrane vesicles /IOV/, in the absence of Mg2+, the only calcium-induced labelling by γ32P-ATP occurs in a 140–150 000 molecular weight protein fraction, representing the hydroxylamine-sensitive phosphorylated interme

In calmodulin-stripped inside-out human red cell membrane vesicles /IOV/ ATP + Mg 2+ -dependent active calcium uptake is stimulated by the addition of calmodulin. Calmodulin increases the maximum calcium transport rate /V max /, decreases K Ca , and
