Key result
The central mutation site of RyR2 was mapped to a bridge of density connecting cytoplasmic domains 5 and 6, which is distinct from the previously mapped FKBP12.6-binding site.

Central RyR2 mutations act independently of FKBP12.6; extends structural mapping but leaves functional and therapeutic implications open.
The study maps the central mutation site of RyR2 to a specific structural bridge, providing structural insights into mutations linked to sudden cardiac death.
Liu et al. (2005) studied Sudden cardiac death (genetic forms). Green fluorescent protein insertion and cryoelectron microscopy was evaluated on Localization of the central mutation site in the three-dimensional structure of RyR2. The central mutation site of RyR2 was mapped to a bridge of density connecting cytoplasmic domains 5 and 6, which is distinct from the previously mapped FKBP12.6-binding site.
