Prion diseases are
connected with self-replication and self-propagation
of misfolded proteins. The rate-limiting factor is the formation of
the initial seed. We have recently studied the early stages in the
conversion between functional PrPC and the infectious scrapie
PrPSC form, triggered by the binding of RNA. Here, we study
how this process is modulated by the prion sequence. We focus on residues
129 and 178, which are connected to the hereditary neurodegenerative
disease fatal familial insomnia.
Abstract:Prion diseases are connected with self-replication and self-propagation of mis-folded proteins.The rate-limiting factor is the formation of the initial seed. We have recently studied early stages in the conversion between functional PrP C and the infectious scrapie PrP SC form, triggered by the binding of RNA. Here, we study how this process is modulated by the prion sequence. We focus on residues 129 and 178, which are connected to the hereditary neurodegenerative disease Fatal Familial Insomnia.peer-reviewed)
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.
