Beta1-Adrenergic Receptor Regulation Revisited

Susan F Steinberg. Circ Res. .

Abstract

The actions and regulation of cardiomyocyte β1ARs differ in several respects from the properties described for the prototypical β2AR subtype; a mechanism to explain the unique properties of the β1AR subtype has never been obvious. This viewpoint summarizes recent studies that identify a novel signaling paradigm for the β1AR, implicating the N-terminus as a molecular determinant of β1AR responsiveness.

Keywords: apoptosis; arrestin; catecholamine; heart failure; immunoblotting.
