The mechanisms of adrenergic stimulation of cardiac voltage-gated calcium (CaV) channels have remained elusive. Using proximity proteomics and genetically altered mice, we show that phosphorylation of the CaV channel inhibitor Rad is essential for regulation, by the sympathetic nervous system, of calcium influx, and for augmentation of cardiac contractility.
