Liquid-like protein assemblies initiate endocytosis


Endocytosis is critical for regulating plasma membrane composition and function. The mechanisms that control the assembly and dynamic rearrangement of the endocytic protein network to enable endocytic vesicle formation have remained elusive. Two endocytic initiator proteins are now shown to form liquid-like condensates to initiate endocytosis.
