The skeletal muscle ryanodine receptor isoform 1 (RyR1) is a calcium release channel involved in excitation-contraction coupling, the process whereby an action potential is translated to a cytoplasmic Ca2+ signal that activates muscle contraction. Dominant and recessive mutations in RYR1 cause a range of muscle disorders, including malignant hyperthermia and several forms of congenital myopathies. Many aspects of disease pathogenesis in ryanodinopathies remain uncertain, particularly for those myopathies due to recessive mutations. A thorough understanding of the ryanodine receptor macromolecular complex and its interactions with proteins and small molecular modulators is an essential starting point from which to investigate disease mechanisms. © 2012 Elsevier Ltd.

Abstract
The skeletal muscle ryanodine receptor isoform 1 (RyR1) is a calcium release channel involved in excitation-contraction coupling, the process whereby an action potential is translated to a cytoplasmic Ca2+ signal that activates muscle contraction. Dominant and recessive mutations in RYR1 cause a range of muscle disorders, including malignant hyperthermia and several forms of congenital myopathies. Many aspects of disease pathogenesis in ryanodinopathies remain uncertain, particularly for those myopathies due to recessive mutations. A thorough understanding of the ryanodine receptor macromolecular complex and its interactions with proteins and small molecular modulators is an essential starting point from which to investigate disease mechanisms. © 2012 Elsevier Ltd.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
