Surface receptors can link binding of ligands to changes in the actin-based cell cytoskeleton. Chia etal. and Chen etal. provide evidence for direct binding between the cytoplasmic tails ofreceptorsand the WAVE complex, a regulator of the actin nucleator Arp2/3 complex, which mighthelp to explain how environmental signals are translated into changes in morphology andmotility.
