Prions are important disease agents and epigenetic regulatory elements. Prion formation involves the structural conversion of proteins from a soluble form into an insoluble amyloid form. In many cases, this structural conversion is driven by a glutamine/asparagine (Q/N)-rich prion-forming domain. However, our understanding of the sequence requirements for(More)
Previously the expression of Protein Tyrosine Phosphatase Interacting Protein 51 (PTPIP51) in mouse brain was reported. Here, we investigated PTPIP51 mRNA and protein in two of the brain regions namely the hippocampus and the cerebellum of mouse brains. On a cellular level both the protein and the mRNA were related to the pyramidal cells of the hippocampal(More)
Protein tyrosine phosphatase interacting protein 51 (PTPIP51) is upregulated in glioblastoma multiforme (GBM) and expression levels correlate with the grade of malignancy in gliomas. A similar correlation was reported for its interacting partner 14-3-3β, which has been shown to facilitate the interaction of PTPIP51 with cRAF (Raf1). Since the interaction of(More)
Prion formation involves the conversion of proteins from a soluble form into an infectious amyloid form. Most yeast prion proteins contain glutamine/asparagine-rich regions that are responsible for prion aggregation. Prion formation by these domains is driven primarily by amino acid composition, not primary sequence, yet there is a surprising disconnect(More)
