ERK1/2 mediates insulin stimulation of Na,K-ATPase by phosphorylation of the α-subunit in human skeletal muscle cells
Insulin stimulates Na+,K+-ATPase activity and induces translocation of Na+,K+-ATPase molecules to the plasma membrane in skeletal muscle. We determined the molecular mechanism by which insulin regulates Na+,K+-ATPase in differentiated primary human skeletal muscle cells (HSMCs). Insulin action on Na +,K+-ATPase was dependent on ERK1/2 in HSMCs. Sequence analysis of Na+,K+-ATPase α-subunits reveale
