In the study by Samsó et al. (2005), the RyR Ryanodine Receptor's molecular structure is elucidated, revealing a cylinder 10 Å long and 8 Å in diameter. With 4 negative charges and 13 M of charge, as well as 8 oxygens with charge -1/2, the receptor's complex architecture occupies 18% of its available volume, making it a very crowded environment. Key findings highlight the presence of aspartate residues and offer valuable insights into the receptor's function.
