A, B	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
