Major vault protein is a protein that in humans is encoded by the MVP gene.[5][6] 78 copies of the protein assemble into the large compartments called vaults.

Function

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. It is widely distributed in normal tissues, and overexpressed in multidrug-resistant cancer cells. The protein overexpression is a potentially useful marker of clinical drug resistance. This gene produces two transcripts by using two alternative exon 2 sequences; however, the open reading frames are the same in both transcripts.[6]

Interactions

Major vault protein has been shown to interact with Estrogen receptor alpha,[7] PTEN[8] and PARP4.[9][10]
