Abstract

Prion diseases are associated with the misfolding of the endogenously expressed prion protein (designated PrPC) into an abnormal isoform (PrPSc) that has infectious properties. The hydrophobic domain of PrPC is highly conserved and contains a series of glycine residues that show perfect conservation among all species, strongly suggesting it has functional and evolutionary significance. These glycine residues appear to form repeats of the GXXXG protein-protein interaction motif (two glycines separated by any three residues); the retention of these residues is significant and presumably relates to the functionality of PrPC. Mutagenesis studies demonstrate that minor alterations to this highly ..
