Title: Role of phosphorylation clusters in the biology of the coronavirus infectious bronchitis virus nucleocapsid protein Cord-id: wovftw3l Document date: 2008_1_20

Snippet: The coronavirus infectious bronchitis virus (IBV) nucleocapsid (N) protein is an RNA binding protein which is phosphorylated at two conserved clusters. Kinetic analysis of RNA binding indicated that the C-terminal phosphorylation cluster was involved in the recognition of viral RNA from non-viral RNA. The IBV N protein has been found to be essential for the successful recovery of IBV using reverse genetics systems. Rescue experiments indicated that phosphorylated N protein recovered infectious I
Document: The coronavirus infectious bronchitis virus (IBV) nucleocapsid (N) protein is an RNA binding protein which is phosphorylated at two conserved clusters. Kinetic analysis of RNA binding indicated that the C-terminal phosphorylation cluster was involved in the recognition of viral RNA from non-viral RNA. The IBV N protein has been found to be essential for the successful recovery of IBV using reverse genetics systems. Rescue experiments indicated that phosphorylated N protein recovered infectious IBV more efficiently when compared to modified N proteins either partially or non-phosphorylated. Our data indicate that the phosphorylated form of the IBV N protein plays a role in virus biology.
