This probably isn't possible as the folding of PrP is not encoded in the mRNA of PRNP. The fold of PrP is a post-translational phenomenon, much like its glycosylation. This is true for many mammalian proteins, especially cell-surface proteins.

I’m aware of that. However the specific choice of amino acids can heavily influence the propensity to fold in a particular way. For example homozygotes for M129 have a much faster rate of vCJD development. Since Prion Diseases occur sporadically, the rate of mis folding can be increased and it probably wouldn’t be that difficult (even computationally) to determine how you can get it to misfold at a much higher rate.

I’m not sure what you mean by the fold being post translational, all folding is post translational, it’s literally the protein curling up into the lowest energy conformation as soon as it encounters the cellular environment, with assistance from HSPs if necessary. Unless you meant something else?
