The Structure of a beta-Catenin Binding Repeat from Adenomatous Polyposis Coli (APC) in Complex with beta-Catenin

The structure was published by Eklof Spink, K., Fridman, S.G., and Weis, W.I., in 2001 in a paper entitled "Molecular mechanisms of beta-catenin recognition by adenomatous polyposis coli revealed by the structure of an APC-beta-catenin complex." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 3.1 Å and deposited in 2001.

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 ADENOMATOUS POLYPOSIS COLI PROTEIN.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule has more than one probable quaternary state observed. For more details see the quaternary structure page.
