Note: As the T2 protein of Orbiviruses had important functions in virus protein/RNA structure and assembly, amino acid homology analysis for the T2 protein of TIBOV (T2 = VP3) compared to the T2 proteins of the above mentioned orbiviruses is presented:
AHSV-4(T2 = VP3):58.5%; BTV-6(T2 = VP3):75.9%; EHDV-6(T2 = VP3):75.8%; PALV(T2 = VP3):58.0%;
SCRV(T2 = VP2):22.9%; YUOV(T2 = VP2):37.6%.
