Abstract

Compartmentalization of signaling enzymes allows cardiomyocytes to make contextually specific decisions using a common set of second messengers. Though first identified by their role in localizing the pleiotropic cAMP-dependent protein kinase A (PKA) to specific intracellular organelles and compartments, A-kinase-anchoring proteins (AKAPs) are a structurally and functionally diverse family of multivalent scaffolds that organize “signalosomes” constituting critical nodes in the cell-type-specific network of intracellular signaling pathways. This chapter summarizes the role of AKAPs in cardiomyocytes, with a focus on the intersection of compartmentalized signaling and cardiac pathophysiology.
