Abstract:

To study the interactions between the classical swine fever virus (CSFV) and the host,coimmunoprecipitation (Co-IP) and subsequent mass spectrometry were used to screen and identify the host proteins interacted with CSFV C protein from PK-15 cells.β-actin was identified as a potential interacting partner of C protein.In addition,the interaction of the two proteins was further confirmed by endogenous Co-IP and GST pulldown.Moreover,laser confocal imaging confirmed that β-actin colocalized with the CSFV C protein in the cytoplasm.These results showed that CSFV C interacted with β-actin which would facilitate further study of interactions between CSFV proteins and host cell proteins.
