(PrP) a 33?5 kD protein of uncertain function, in humans coded for by a gene on the short arm of chromosome 20. The 27?0 kD protease-resistant core is the functional, and perhaps only, component of prions; several isoforms have been identified and are responsible for prion disease. Extracellular prion protein aggregates into rod-shaped structures that resemble amyloid.
