Observation of Network Dynamics of Ryanodine Receptors on Skeletal Muscle Sarcoplasmic Reticulum Membranes

Rabbit muscle vesicles derived from sarcoplasmic reticulum were used as a material in studying networks of ryanodine receptors by cryo electron tomography. Three-dimensional analysis reveals the dynamical features of these networks. It was found that the connection angles were rotated along the tran...

description Rabbit muscle vesicles derived from sarcoplasmic reticulum were used as a material in studying networks of ryanodine receptors by cryo electron tomography. Three-dimensional analysis reveals the dynamical features of these networks. It was found that the connection angles were rotated along the transmembrane axis of ryanodine receptors. Majority of the connections was observed at domains 6/6 of ryanodine receptors while a small group of connections were showed at domains 9/10. The flexible rotation and connection shift seem to facilitate the extension of an annular network on the wall of the sarcoplasmic reticulum in a triad.
