== Function ==
[https://www.uniprot.org/uniprot/Q3HNQ2_RHDV Q3HNQ2_RHDV] 3C-like protease processes the polyprotein: 3CLpro-RdRp (p72) is first released by autocleavage, then all other proteins are cleaved.[ARBA:ARBA00003176]  Capsid protein VP60 self assembles to form an icosahedral capsid with a T=3 symmetry, about 35 nm in diameter, and consisting of 180 capsid proteins. A smaller form of capsid with a diameter of 23 nm might be capsid proteins assembled as icosahedron with T=1 symmetry. The capsid encapsulate VP2 proteins and genomic or subgenomic RNA. Attaches virion to target cells by binding histo-blood group antigens, inducing endocytosis of the viral particle. Acidification of the endosome induces conformational change of capsid protein thereby injecting virus genomic RNA into host cytoplasm.[ARBA:ARBA00024666]  NTPase presumably plays a role in replication. Despite having similarities with helicases, does not seem to display any helicase activity.[ARBA:ARBA00025124]  Viral genome-linked protein is covalently linked to the 5'-end of the positive-strand, negative-strand genomic RNAs and subgenomic RNA. Acts as a genome-linked replication primer. May recruit ribosome to viral RNA thereby promoting viral proteins translation.[ARBA:ARBA00025359]
