The phosphorylation status of SRC is altered in response to various injurious factors or stress stimuli and regulates different cardiac pathological states, such as hypertension, coronary heart disease, ischemic heart disease, MI-reperfusion injury, arrhythmias, and cardiomyopathy, by modulating cell growth, differentiation, motility, function, and electrophysiological signaling. Here, SRC is linked to cardiomyopathy.
