| + | Sevenless (Sev) is a Drosophila receptor tyrosine kinase (RTK) required for the specification of the R7 photoreceptor. It is cleaved into alpha and beta subunits and binds the ectodomain of the G-protein-coupled receptor bride of sevenless (Boss). Previous work showed that the Boss ectodomain could bind but not activate Sev; rather, the whole seven-pass transmembrane Boss was required. Here, we show that Sev does not need to be cleaved to function and that a single-pass transmembrane form of Boss activates Sev. We use cryo-electron microscopy and biophysical methods to determine the structural basis of ligand binding and pH-dependent dimerization of Sev, and we discuss the implications in the process of Sev activation. The Sev human homolog, receptor oncogene from sarcoma 1 (ROS1), is associated with oncogenic transformations, and we discuss their structural similarities. | ||
