主 题:FMDV VP1 protein KIF5B Endosome Clathrin
摘 要:Foot-and-mouth disease(FMD)is a highly contagious and economically important disease,which is caused by the FMD virus(FMDV).Although the cell receptor for FMDV has been identified,the specific mechanism of FMDV internalization after infection remains *** this study,we found that kinesin family member 5B(KIF5B)plays a vital role during FMDV ***,we confirmed the interaction between KIF5B and FMDV structural protein VP1 by co-immunoprecipitation(Co-IP)and co-localization in FMDV-infected *** particular,the stalk[amino acids(aa)413–678]domain of KIF5B was indispensable for KIF5B-VP1 ***,overexpression of KIF5B dramatically enhanced FMDV replication;consistently,knockdown or knockout of KIF5B suppressed FMDV ***,we also demonstrated that KIF5B promotes the internalization of FMDV via regulating clathrin ***5B also promotes the transmission of viral particles to early and late endosomes during the early stages of *** conclusion,our results demonstrate that KIF5B promotes the internalization of FMDV via regulating clathrin uncoating and intracellular *** study may provide a new therapeutic target for developing FMDV antiviral drugs.
