Polyamines and neomycin inhibit the purified plasma-membrane Ca2+ pump by interacting with associated polyphosphoinositides.
We investigated the effect of spermine, spermidine, putrescine and neomycin on the activity of the plasma-membrane Ca2+ pump and on its stimulation by negatively charged phospholipids and calmodulin. Millimolar concentrations of spermine and to a lesser extent of spermidine decreased the ATPase acti...
