Prion proteins play powerful role in survival, evolution of wild yeast strains
Prions, the much-maligned proteins most commonly known for causing "mad cow" disease, are commonly used in yeast to produce beneficial traits in the wild. Moreover, such traits can be passed on to subsequent generations and ...

PRNP
More reference expression data
PRNP (PRioN Protein (Creutzfeld-Jakob disease, Gerstmann-Sträussler-Scheinker syndrome, fatal familial insomnia)) is a gene that codes for a protein called the prion protein (PrP), which is expressed in the brain and several other tissues.
The human PRNP gene is located on the short (p) arm of chromosome 20 between the end (terminus) of the arm and position 12, from base pair 4,615,068 to base pair 4,630,233.
PRNP has also recently been designated CD230 (cluster of differentiation 230).
