Structure of the ankyrin binding domain of a -Na, K-ATPase

摘要

The present invention provides a polypeptide of 26 amino acid residues that comprises the minimal ankyrin binding (MAB) domain. The MAB domain is responsible for the interactions between a Na,K-ATPase and ankyrin. The present invention also provides the three dimensional structure of the MAB domain. Also provided by the present invention are methods for modulating the interaction of a Na,K-ATPase and ankyrin.
