NHE- and diffusion-dependent proton fluxes across the tubular system membranes of fast-twitch muscle fibers of the rat Academic Article uri icon

abstract

  • The regulation of pH across the t-system membrane of skeletal muscle fibers is poorly understood. Using a sealed tubule preparation, Launikonis et al. reveal Na+/H+ exchange activity and characterize the properties of the diffusional and NHE proton fluxes across the t-system.
