Mammalian prion protein folding
WebThe GGGTHSQW sequence in the amyloidogenic part of the prion protein is a potential binding site for Cu(II). We have previously studied the binding of copper to the shorter GGGTH peptide and showed that it is highly pH dependent (Hureau et al. in J. Biol. Inorg. Chem. 11:735-744, 2006). WebTwo well studied cases of β-helix folding mechanism, Pertactin and P22 tailspike protein, have shown to exhibit very long folding times in vitro, probably the longest reported so far. Citation 66 – Citation 68 The β-helix fold in these proteins is achieved in the monomer itself, as opposed to PrP which seems to form a multimeric β-helix.
