The cysteine-rich region of type VII collagen is a cystine knot with a new topology

Henrik Wegener, Hauke Paulsen, Karsten Seeger

Abstract

Background: Type VII collagen is essential for skin stability as highlighted by related skin blistering diseases.Results: A fusion protein comprising the cysteine-rich region and parts of the flanking domains forms a trimer upon oxidization.Conclusion: The cysteine-rich region is an N-terminal cystine knot with novel topology.Significance: The cystine knot is also found in type IX collagen, indicating a general principle.
