The vault is a ubiquitous and highly conserved ribonucleoprotein particle of approximately 13 mDa of unknown function [1]. This family corresponds to a repeated domain found in the amino terminal half of the major vault protein.
This domain is found in the Major Vault Protein and has been called the shoulder domain [1]. This family includes two bacterial proteins Swiss:A6FXE2 and Swiss:A1ZGE7. This suggests that some bacteria may possess vault particles.

This entry represents the major vault protein interaction domain (MVP-ID) at the C-terminal in PARP4 proteins. These proteins mediate mono-ADP-ribosylation of target proteins. This enzymatic activity involves the transfer of ADP-ribose units to specific proteins, which can influence various cellular processes. PARP4 proteins are components of the vault ribonucleoprotein particle, a complex that includes major vault protein (MVP) and vault RNAs (vRNAs). They also interact with TEP1, which suggests a role in cellular transport or signalling pathways [1]. The MVP-ID domain facilitates PARP4 interaction with the Major Vault Protein (MVP) and localisation inside the vault ribonucleoprotein complex. It is predicted to contain an helical structure [2].
