Beta-catenin binding domain of Axin in complex with beta-catenin

The structure was published by Xing, Y., Clements, W.K., Kimelman, D., and Xu, W., in 2003 in a paper entitled "Crystal structure of a beta-catenin/Axin complex suggests a mechanism for the {beta}-catenin destruction complex" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2003.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely Beta-catenin and Axin.
