Major vault protein is a protein that in humans is encoded by the MVP gene. 78 copies of the protein assemble into the large compartments called vaults illustrated and discussed in the article on Vault (organelle).This gene encodes the major vault protein which is a lung infection resistance-related protein. Vaults are multi-subunit structures that may be involved in nucleo-cytoplasmic transport. This protein mediates drug resistance perhaps via a transport process.
