In many non rodent species, low concentrations of this substance (i.e., in the subnanomolar range) may stimulate the Na-K-ATPase. The mechanism of the stimulatory effect is not understood and remains controversial. Further, the issue in rodents is more complicated because there are different isoforms of the Na-K-ATPase - some of which are very sensitive to ouabain while others are not.
