Bone-cell regulation, fleshed out One of many medically relevant G protein–coupled receptors, parathyroid hormone receptor-1 (PTH1R) functions in the control of calcium homeostasis and bone physiology. Zhao et al. used cryo–election microscopy to observe the structure of PTH1R in a complex with a modified form of parathyroid hormone and stimulatory G protein. The structural model helps explain how parathyroid hormone interacts with its receptor and the molecular basis for receptor activation. Science , this issue p. 148
