We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| + | Vaults are ubiquitous ribonucleoprotein particles involved in a diversity of cellular processes, with promising applications as nanodevices for delivery of multiple cargos. The vault shell is assembled by the symmetrical association of multiple copies of the major vault protein that, initially, generates half vaults. The pairwise, anti-parallel association of two half vaults produces whole vaults. Here, using a combination of vault recombinant reconstitution and structural techniques, we characterized the molecular determinants for the vault opening process. This process commences with a relaxation of the vault waist, causing the expansion of the inner cavity. Then, local disengagement of amino-terminal domains at the vault midsection seeds a conformational change that leads to the aperture, facilitating access to the inner cavity where cargo is hosted. These results inform a hitherto uncharacterized step of the vault cycle and will aid current engineering efforts leveraging vault for tailored cargo delivery. | ||
