Function

POLG_RHDVF NTPase presumably plays a role in replication (By similarity).[1] [2] 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 (By similarity).[3] [4] 3C-like protease processes the polyprotein: 3CLpro-RdRp (p72) is first released by autocleavage, then all other proteins are cleaved (By similarity).[5] [6] RNA-directed RNA polymerase replicates genomic and antigenomic RNA by recognizing replications specific signals. Transcribes also a subgenomic mRNA by initiating RNA synthesis internally on antigenomic RNA. This sgRNA codes for structural proteins. Catalyzes the covalent attachment VPg with viral RNAs (By similarity).[7] [8] 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 (By similarity).[9] [10]
