    Abstract: Vaults are cytoplasmic ribonucleoprotein organelles that are highly conserved among diverse eukaryotic species. Their mass (12.9 MDa), diameter (26-35 nm) and shape (two halves, each with eightfold radial symmetry) have recently been determined and are similar to those ascribed to the central plug (or transporter) of the nuclear pore complex (NPC). The size and eightfold symmetry of the vault particle make it conducive to interacting physically in a complementary manner with NPCs. The present study demonstrates that vaults specifically associate with nuclei by both immunoblotting and immunofluorescence. Immunogold EM confirmed that vaults associate with the nuclear envelope in tissue sections and with NPCs of isolated nuclei.

    Abstract: We first reported on the existence of vault ribonucleoprotein particles in 1986, and since this study we have demonstrated that these unusual RNPs are ubiquitously expressed and highly conserved among diverse eukaryotes. These particles are quite large (65 x 35 nm) and distinctly regular in shape and dimensions. The polypeptide composition of vaults is also similar between species, dominated by a∼100 Kd protein which makes up 〉 70% of the particles mass. The RNA component of vaults, which has been sequenced and characterized from both rat and bullfrog, does not appear to serve a structural role, and due to the strong conservation of its secondary structure could serve a functional role.
