Synergistic interactions between aqueous and membrane domains of a designed protein determine its fold and stability.

Abstract excerpt

Membrane-spanning proteins contain both aqueous and membrane-spanning regions, both of which contribute to folding and stability. To explore the interplay between these two domains we have designed and studied the assembly of coiled-coil peptides that span from the membrane into the aqueous phase. The membrane-spanning segment is based on MS1, a transmembrane coiled coil that contains a single Asn at a buried a...
