Area of Science:

  • Biochemistry
  • Neuroscience
  • Molecular Biology

Background:

  • Prion protein (PrP(C)) misfolding is central to prion diseases.
  • Understanding PrP(C) interactions is crucial for developing therapeutic interventions.

Purpose of the Study:

  • To identify proteins interacting with bovine mature prion protein (PrP(C)).
  • To investigate the functional relationship between alphaB-crystalline and PrP(C).

Main Methods:

  • Yeast two-hybrid assay using bovine PrP(C) as bait.
  • In vivo and in vitro validation including immunofluorescent colocalization, native polyacrylamide-gel electrophoresis, and IAsys biosensor assays.

Main Results:

  • AlphaB-crystalline was identified as a binding partner of PrP(C).
