PP2A-B56α is a key determinant of cardiac protein phosphorylation and functional responses to β-adrenergic signalling
{{output}}
B56α is a protein phosphatase 2 A (PP2A) regulatory subunit which modulates the heart's inotropic response to acute β-adrenergic receptor (β-AR) stimulation, although knowledge of the underlying molecular mechanisms is limited. In this study, mice deficien... ...
