May act as a scaffold protein in virion assembly. May also play a role in intracellular signaling during viral replication (By similarity). H2O + O-phospho-L-tyrosyl-[protein] = L-tyrosyl-[protein] + phosphate H2O + O-phospho-L-seryl-[protein] = L-seryl-[protein] + phosphate H2O + O-phospho-L-threonyl-[protein] = L-threonyl-[protein] + phosphate VP1 and VP2 are detected 12 hours post infection, while VP3 only after 24 hours. Belongs to the gyrovirus protein VP2 family.
