Adapter proteins assist clathrin coated pit assembly. Here, the authors combine native mass spectrometry, crystallography and SAXS measurements and show that the membrane–proximal domains of the adaptor proteins epsin and Sla2 form complexes mediated through phosphatidylinositol 4,5-bisphosphate interfaces leading to assembly formation.
