Inter-Organelle Interactions between the ER and Mitotic Apparatus Facilitates Zika Protease Cleavage of Human Kinesin-5 and Contributes to Distinct Mitotic Defects
Abstract:Zika virus infection can result in profound fetal deficits, such as microcephaly and blindness. Here we identify Kif11/Kinesin-5, as a cellular target of Zika protease with both in vitro and in vivo assays. We show that soluble Zika NS2-3 protease chimera targets several sites within the motor domain of HsEg5 either when free in solution or rigor-bound to microtubules. We tested two different forms of the protease in human cells. First, we find that soluble Zika protease chimera is cytotoxic and eventually lea… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
