## Abstract Red blood cells contain a protein that activates membraneโbound (Ca^2+^ + Mg^2+^)โATPase and Ca^2+^ transport. The red blood cell activator protein is similar to a modulator protein that stimulates cyclic AMP phosphodiesterase. Wang and Desai [Journal of Biological Chemistry 252:4175โ41

## Abstract Human red blood cells (RBC) contain a cytoplasmic, nonhemoglobin protein which activates the (Ca^2+^โMg^2+^) ATPase of isolated RBC membranes. Results presented in this paper confirm that activation of (Ca^2+^โMg^2+^)ATPase is associated with binding of the cytoplasmic activator to the
The effect of pinacidil, an opener of ATP-sensitive K + (K ATP ) channels, on large-conductance Ca 2+ -activated K+ (BK Ca ) channels was investigated in cultured endothelial cells of human umbilical veins. In whole cell configuration, pinacidil (30 ยตM) increased the amplitude of K + outward current
The cell-attached and excised patch configurations of the patch clamp technique were used to characterize Ca 21 -activated maxi-K 1 channels in freshly isolated Mu ยจller glial cells. The cells were dissociated from postmortem adult human and porcine retinas. The maxi-K 1 channels in Mu ยจller cells o
## Abstract The human mast cell line (HMCโ1) has been used to study the relationship between intracellular pH and cytosolic calcium (Ca^2+^) in mast cells. Thapsigargin (TG) caused storeโoperated Ca^2+^ entry, that is enhanced by the PKC activator PMA. NH~4~Clโinduced alkalinization showed an inhib
