title: Isoform-Specific Regulation of the Na(+)-K(+) Pump in Heart.
abstract: Guinea pig ventricular myocytes coexpress two isoforms of the Na(+)-K(+) pump. These two isoforms respond differently to the physical environment and are coupled to autonomic input through different signal transduction cascades. The expression of different isoforms provides each cell type with a mechanism of programming specific responses to environmental changes.
