Abstract

Na+/K+-ATPase (NKA) plays the key role in maintaining Na+ and K+ gradients in cells, which is essential for regulation of cell volume and membrane potential. PLM (aka FXYD1) interacts with NKA and Na+/Ca2+ exchanger (NCX) and modulates their activities in tissue specific and physiological state specific manner. Protein kinase A (PKA) and protein kinase C (PKC) targets different pools of PLM associated with NKA and NCX, thereby regulating their activities. Additionally, some signal transducers such as phosphatases, phosphodiesterases and nitric oxide play important roles in modulating functions of PLM, especially under phosphorylated conditions, toward the activities of NKA and NCX. Understanding the above phenomenon is of significance in developing novel therapeutics for recovery of patients suffering from a variety of pathophysiological conditions, especially cardiovascular and neural diseases.
