== Publication Abstract from PubMed == | |||
How the endoplasmic reticulum (ER) folding machinery coordinates general and specialized chaperones during protein translation and folding remains an important unanswered question. Here, we show two structural domains in MESD, a specialized chaperone for LRP5/6, carry out dual functions. The chaperone domain forms a complex with the immature receptor, maintaining the beta-propeller (BP) domain in an interaction competent state for epidermal growth factor-repeat binding. This promotes proper folding of the BP domain, causing a binding switch from the chaperone domain to the escort domain. The escort complex ensures LRP5/6 safe-trafficking from the ER to the Golgi by preventing premature ligand-binding. Inside the Golgi, the BP domain may contain a histidine switch, regulating MESD dissociation and retrieval. Together, we generate a plausible cell biology picture of the MESD/LRP5/6 pathway, suggesting that it is the specialized chaperones, MESD, that serves as the folding template to drive proper folding and safe trafficking of large multidomain proteins LRP5/6. | |||
