Protein Domain : Hepatitis TT virus, Orf2/Gyrovirus Vp2 IPR004118

Type	Family
Description	This entry represents the Gyroviral VP2 protein and TT viral ORF2.Torque teno virus (TTV) is a nonenveloped and single-stranded DNA virus that was initially isolated from a Japanese patient with hepatitis of unknown aetiology, and which has since been found to infect both healthy and diseased individuals [ ]. Numerous prevalence studies have raised questions about its role in unexplained hepatitis. ORF2 is a 150 residue protein of unknown function. Gyroviruses are small circular single stranded viruses, such as the Chicken anaemia virus. The VP2 protein contains a set of conserved cysteine and histidine residues suggesting a zinc binding domain. VP2 may act as a scaffold protein in virion assembly and may also play a role in intracellular signaling during viral replication.
