ENTH/ANTH domains expand to the Golgi.
Clathrin-coated vesicles (CCVs) play important roles in nutrient uptake, downregulation of signaling receptors, pathogen invasion and biogenesis of endosomes and lysosomes. Although detailed models for endocytic CCV formation have emerged, the process of CCV formation at the Golgi and endosomes has been less clear. Key to endocytic CCV formation are proteins containing related phosphoinositide-binding ENTH and ANTH domains. Now, recent studies have identified novel ENTH/ANTH proteins that participate in CCV-mediated traffic between the trans-Golgi Network (TGN) and endosomes and have defined a molecular basis for interaction with AP-1 and GGA adaptors in clathrin coats of the TGN/endosomes. Thus, ENTH/ANTH domain proteins appear to be universal elements in nucleation of clathrin coats.
