In response to excitation of skeletal muscle fibers, trains of action potentials induce changes in the configuration of the dihydropyridine receptor (DHPR) anchored in the tubular membrane which opens the Ca2+ release channel in the sarcoplasmic reticulum membrane. The DHPR also functions as a voltage-gated Ca2+ channel that conducts L-type Ca2+ currents routinely recorded in mammalian muscle fibers, which role was debated for more than four decades. Recently, to allow a closer look into the role of DHPR Ca2+ influx in mammalian muscle, a knock-in (ki) mous
