Chains	Accession	Name	Description	Comments	Source
A, B	PF01505	Major Vault Protein repeat domain (Vault)	Major Vault Protein repeat domain	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.	Domain
A, B	PF17794	Major Vault Protein repeat domain (Vault_2)	Major Vault Protein repeat domain	This short domain is found repeated numerous times in the Major Vault Protein. This entry is related to Pfam:PF01505.	Domain
A, B	PF17795	Major Vault Protein Repeat domain (Vault_3)	Major Vault Protein Repeat domain	This domain is found in the Major Vault Protein.	Domain
A, B	PF17796	Major Vault Protein repeat domain (Vault_4)	Major Vault Protein repeat domain		Domain
A, B	PF11978	Shoulder domain (MVP_shoulder)	Shoulder domain	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.	Domain
