Abstract

In the present paper we show that distinct human RyR2 (ryanodine receptor type 2) inherited mutations expressed in mammalian cells exhibit either unaltered or increased FKBP12.6 (12.6 kDa FK506-binding protein) binding compared with the wild-type. Oxidizing conditions result in decreased FKBP12.6 binding, but to the same extent as for the wild-type. Our findings suggest that FKBP12.6 regulation of RyR2 is unlikely to be the primary defect in inherited arrhythmogenic cardiac disease.
