Protein attributes

Sequence length	216 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	May act as a scaffold protein in virion assembly. May also play a role in intracellular signaling during viral replication By similarity.
Catalytic activity	Protein tyrosine phosphate + H2O = protein tyrosine + phosphate. A phosphoprotein + H2O = a protein + phosphate.
Induction	VP1 and VP2 are detected 12 hours post infection, while VP3 only after 24 hours.
Sequence similarities	Belongs to the gyrovirus protein VP2 family.
