abstract：:We have recently reported that α(2)β(1) and α(1)β(1) isozymes of Na(+)/K(+)-ATPase (NKA) are localized in the caveolae whereas only the α(1)β(1) isozyme of NKA is localized in the non-caveolae fraction of pulmonary artery smooth muscle cell membrane. It is well known that different isoforms of NKA are regulated differ...
