Identification of the interaction between vimentin and nucleocapsid protein of transmissible gastroenteritis virus.
Nucleocapsid (N) protein of transmissible gastroenteritis virus (TGEV) packages viral RNA genome to form a ribonucleoprotein complex. In addition to its function as a structural protein, N protein is involved in cell apoptosis or cell-cycle regulation. N protein possibly interacts with host factors to modulate cellular functions. To identify cellular proteins that interacted with N protein of TGEV, methods of GST pull-down and Co-IP were utilized to precipitate cellular proteins of swine testicular (ST). Bound cellular proteins were resolved by SDS-PAGE. Analysis of interacting proteins by mass spectrometry allowed identification of 15 cellular protein bands representative of 12 cellular proteins including vimentin that bound to N protein. Furthermore, the function of vimentin cytoskeleton in ST cells during TGEV infection was examined. Vimentin cytoskeleton was required for virus replication. The present study thus provides protein-related information about interaction of TGEV N protein with host cell that should be useful for understanding host cell response to coronavirus pathogenesis infection and the underlying mechanism of coronavirus replication.
