Blog Post #2 BLAST Protein Sequence - Alanna Barnett

  1. The protein I chose to search for this assignment was a prion protein; ideally a human prion protein. Given that these proteins have the potential for catastrophic damage to the brain when folded improperly, I thought they would make an interesting choice.
  2. The particular prion protein (PrP) that I used was the Prion Protein [Homo Sapiens], accession AAH22532.

  1. Please ignore the terrible spacing between bullet points, I can't seem to fix it.

  2. Interesting that one small protein can do such damage. did you research any possible outcomes of this protein when it is misconstructed?
