Anti-HHAV Protease 3C Polyclonal Antibody

Genome polyprotein (Protease 3C) is a ~251 kDa protein. Capsid proteins VP1, VP2, and VP3 form a closed capsid enclosing the viral positive strand RNA genome. All these proteins contain a beta-sheet structure called beta-barrel jelly roll. Together they form an icosahedral capsid (T=3) composed of 60 copies of each VP1, VP2, and VP3, with a diameter of approximately 300 Angstroms. VP1 is situated at the 12 fivefold axes, whereas VP2 and VP3 are located at the quasi-sixfold axes. The naked capsid interacts with the host receptor HAVCR1 to provide virion attachment to and probably entry into the target cell.
