Stimulus-specific differences in protein kinase C delta localization and activation mechanisms in cardiomyocytes.


Protein kinase C (PKC) isoforms play key roles in the regulation of cardiac contraction, ischemic preconditioning, and hypertrophy/failure. Models of PKC activation generally focus on lipid cofactor-induced PKC translocation to membranes. This study identifies tyrosine phosphorylation as an additional mechanism that regulates PKC delta actions in… (More)
