    • Effects of ATP, Mg2+, and redox agents on the Ca2+ dependence of RyR channels from rat brain cortex 
      Bull Simpfendorfer, Ricardo; Finkelstein, José Pablo; Humeres, Alexis; Behrens Pellegrino, María Isabel; Hidalgo Tapia, María Cecilia (AMER PHYSIOLOGICAL SOC, 2007-07)
      Despite their relevance for neuronal Ca2+-induced Ca2+ release (CICR), activation by Ca2+ of ryanodine receptor (RyR) channels of brain endoplasmic reticulum at the [ ATP], [Mg2+], and redox conditions present in neurons ...
    • Redox-sensitive stimulation of type-1 ryanodine receptors by the scorpion toxin maurocalcine 
      Ronjat, Michel; Finkelstein, José Pablo; Llanos Vidal, Paola; Montecinos, Luis; Bichraoui, Hicham; Waard, Michel De; Hidalgo Tapia, María Cecilia; Bull Simpfendorfer, Ricardo (Elsevier, 2013)
      The scorpion toxin maurocalcine acts as a high affinity agonist of the type-1 ryanodine receptor expressed in skeletal muscle. Here, we investigated the effects of the reducing agent dithiothreitol or the oxidizing reagent ...
