Signal sequences influence membrane integration of the prion protein.

Abstract excerpt

Biosynthesis of the prion protein at the endoplasmic reticulum generates multiple topological forms. The topology of an individual chain is determined first by the localization of the N terminus and then by potential integration of the transmembrane domain into the lipid bilayer. Here, we provide the first evidence that signal sequences affect the latter of these events by demonstrating that some but not other...
