Activation of G protein–coupled receptors is involved in regulating many cellular responses, but less is known regarding the role of these receptors in the differentiation and maintenance of skeletal muscle. New findings implicate the inhibitor subunit Gαi2 as a vital mediator of myofiber maturation and growth, operating through multiple signaling pathways to selectively stimulate protein synthesis or inhibit cytokine-dependent protein turnover.
