Points to post-phosphorylation mechanisms in PLB-knockout contractile deficits; leaves open translation to human heart failure.
The attenuation of beta-adrenergic contractile responses in PLB-knockout hearts is not caused by altered beta-adrenergic signal transduction or phosphorylation of key myofibrillar and sarcolemmal proteins.
Kiss et al. (1997) studied this question.
