Abstract in another language
Prions are infectious, self-propagating amyloid-like protein aggregates of mammals and fungi. We have studied aggregation propensities of a yeast prion domain in cell culture to gain insights into general mechanisms of prion replication in mammalian cells. Here, we report the artificial transmission of a yeast prion across a phylogenetic kingdom. HA epitope-tagged yeast Sup35p prion domain NM was stably expressed in murine neuroblastoma cells. Although cytosolically expressed NM-HA remained soluble, addition of fibrils of bacterially produced Sup35NM to the medium efficiently induced appearance of phenotypically and biochemically distinct NM-HA aggregates that were inherited by daughter cells. Importantly, NM-HA aggregates also were infectious to recipient mammalian cells expressing soluble NM-HA and, to a lesser extent, to yeast. The fact that the yeast Sup35NM domain can propagate as a prion in neuroblastoma cells strongly argues that cellular mechanisms support prion-like inheritance in the mammalian cytosol.
