NCIt definition : Major vault protein (893 aa, 100 kDa) is encoded by the human MVP gene. This protein
plays a role in both the structure and function of vault ribonucleoprotein complexes.;
NCIt note : The vault ribonucleoprotein particle is a huge cage structure (400 A x 670 A) of 12.9
MDa. It consists of a dimer of half-vaults, each half-vault is comprised of 39 identical
major vault protein (MVP) chains, PARP4 and one or more vault RNAs (vRNAs). (UniProt);
