β-adrenergic receptor signalling in adipocytes stimulates energy expenditure via cAMP-dependent increases in lipolysis and fatty-acid oxidation, and this signalling mechanism is thought to be disrupted in obesity. Here, the cAMP-responsive CREB coactivator Crtc3 is shown to promote obesity in mice by attenuating β adrenergic receptor signalling in adipose tissue.
