Molecular Basis of S100A1 Activation and Target Regulation Within Physiological Cytosolic Ca2+ Levels

The S100A1 protein regulates cardiomyocyte function through its binding of calcium (Ca2+) and target proteins, including titin, SERCA, and RyR. S100A1 presents two Ca2+ binding domains, a high-affinity canonical EF-hand (cEF) and a low-affinity pseudo EF-hand (pEF), that control S100A1 activation. F...
