Abstract:
In excitable tissues, the ryanodine receptor Ca(2+) release channel (RyR) protein complex regulates excitation-contraction coupling, exocytosis, gene expression and apoptosis. Defects in RyR function, in genetic or acquired pathologies, lead to massive disruptions of Ca(2+) release that can be lethal. Therefore, RyR has emerged as a putative therapeutic target and an increasing number of RyR-targeting drugs are currently being tested.Nonetheless this large-size channel is still a mystery in terms of structure, which hinders full characterization of the properties of this central protein. This chapter is dedicated to the methods available to examine RyR structure and function. The aim of the article is to concentrate on contemporary methodologies rather than focusing overtly on the progress that has been achieved using these techniques. Here we review a series of reliable approaches that are routinely employed to investigate this channel. Technical limitations are discussed, and technological developments are presented. This work is not a handbook, but it can be used as a resource and a starting point for the investigation of RyR at different levels of resolution.
