Sodium Kinetics of Na,K-ATPase α Isoforms in Intact Transfected HeLa Cells

Abstract

By participating in the regulation of ion and voltage gradients, the Na-K pump (i.e., Na,K-ATPase) influences many aspects of cellular physiology. Of the four alpha isoforms of the pump, alpha1 is ubiquitous, alpha2 is predominant in skeletal muscle, and alpha3 is found in neurons and the cardiac conduction system. To determine whether the isoforms have… (More)
