Chains	Accession	Name	Description	Comments	Source
A	PF20751	Structural protein 2 second domain (SP2_M)	Structural protein 2 second domain	This entry represents the second domain of structural protein 2 of the hepatitis E virus. This domain has a RIFT like fold. The high basic amino acid content of this protein has lead to the suggestion of a role in viral genomic RNA encapsidation.	Domain
A	PF03014	Structural protein 2 nucleoplasmin-like domain (SP2)	Structural protein 2 nucleoplasmin-like domain	This family represents N-terminal domain of structural protein 2 of the hepatitis E virus. The high basic amino acid content of this protein has lead to the suggestion of a role in viral genomic RNA encapsidation.	Domain
A	PF20752	Structural protein 2 C-terminal domain (SP2_C)	Structural protein 2 C-terminal domain	This entry represents the third domain of structural protein 2 of the hepatitis E virus. This domain has a RIFT-like fold. The high basic amino acid content of this protein has lead to the suggestion of a role in viral genomic RNA encapsidation.	Domain
