Review: Structural biology of cell surface receptor–ligand interactions (COPB)

In recent months, a flurry of papers have come out that reveal new insights into the structural interactions of cell-surface receptors with each other and with their ligands. This timely review by Moussu and Santiago captures the highlights, in case you haven’t been following along. The review features…
