Desmoplakin Loss Leads to PKC- and Src-Mediated Contractile Dysfunction in Cardiomyocytes
Background Mutations in DSP, which encodes the protein desmoplakin, lead to cardiomyopathy with unusually high penetrance that presents with arrhythmias, fibro-fatty infiltration, and eventually heart failure. However, the precise mechanism of contractile dysfunction and dilation are incompletely understood. Here, we i...
