...Daniela Rossi; Stefania Lorenzini; Enrico Pierantozzi; Filip Van Petegem; David Osamwonuyi Amadsun; Vincenzo Sorrentino ABSTRACT Junctin is a transmembrane protein of striated muscles, located at the junctional sarcoplasmic reticulum (SR). It is characterized by a luminal C-terminal tail, through...

... of the sarcoplasmic reticulum (SR) Ca 2+ store where it modifies Ca 2+ signalling in the heart and skeletal muscle through its regulation of ryanodine receptor (RyR) Ca 2+ release channels. Junctin is required for normal muscle function as its knockout leads to abnormal Ca 2+ signalling, muscle dysfunction...

... the sarcoplasmic reticulum is required for normal Ca 2+ handling, but excess diastolic Ca 2+ leak attributed to oxidative stress is thought to lower the threshold of RyR2 for spontaneous sarcoplasmic reticulum Ca 2+ release, thus inducing arrhythmia in pathological situations. Therefore, we examined the RyR2...

When we infected the myofibers with the tsO45 mutant at 39°C, the viral glyco-protein appeared to be localised to the terminal cisternae of the sarcoplasmic reticulum. Upon shifting the cultures...
