Domain

Major vault protein, shoulder domain (IPR021870)

Short name: MVP_shoulder

Domain relationships

None.

Description

The major vault protein is the major polypeptide component of a large cellular ribonuclear protein complex found in the cytoplasm of eukaryotic cells. Several roles for vaults have been proposed. Vault proteins have been associated with development of multi-drug resistance [PMID: 23083532]. They have also being implicated in the regulation of several cellular processes including transport mechanisms, signal transmission and immune responses [PMID: 18759128].

This domain is found in the Major Vault Protein and has been called the shoulder domain [PMID: 19150846]. This family includes two bacterial proteins A6FXE2 and A1ZGE7. This suggests that some bacteria may possess vault particles.
