Abstract excerpt
The ryanodine receptor (RyR)/calcium-release channel on the sarcoplasmic reticulum mediates intracellular calcium release required for striated muscle contraction. RyR2, the predominant isoform in cardiac myocytes, comprises a macromolecular complex that includes calstabin2 (FKBP12.6). Calstabin2, an 11.8-kDa cis-trans peptidyl-prolyl isomerase (apparent molecular mass 12.6 kDa), stabilizes the closed state of...
