Summary
Vaults are large cellular particles with a unique barrel shape. Their function remains unknown, but their structure suggests a role in intracellular transport.
Area of Science:
- Cell Biology
- Molecular Biology
Background:
- Vaults are large ribonucleoprotein particles present in eukaryotic cells.
- They consist of major and minor vault proteins and small untranslated RNAs.
- Vaults exhibit a characteristic hollow barrel-like structure (35 x 65 nm).
Purpose of the Study:
- To review current knowledge on the vault complex.
- To discuss vault structure, components, and potential functions.
Main Methods:
- Literature review of existing research on vaults.
Main Results:
- Vaults are predominantly cytoplasmic, sometimes associating with cytoskeletal elements.
- A small fraction of vaults are found associated with the nucleus.
- The precise cellular function of vault complexes is currently unknown.
Conclusions:
- The distinct morphology and distribution of vaults suggest a potential role in intracellular transport processes.
- Further research is needed to elucidate the exact function of vaults in eukaryotic cells.
