Structure of a beta-TrCP1-Skp1-beta-catenin complex: destruction motif binding and lysine specificity on the SCFbeta-TrCP1 ubiquitin ligase

The structure was published by Wu, G., Xu, G., Schulman, B.A., Jeffrey, P.D., Harper, J.W., and Pavletich, N.P., in 2003 in a paper entitled "Structure of a beta-TrCP1-Skp1-beta-Catenin complex: destruction motif binding and lysine specificity of the SCFbeta-TrCP1 ubiquitin ligase" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.95 Å and deposited in 2003.

The experimental data on which the structure is based was not deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely F-box/WD-repeat protein 1A, Skp1, and Beta-catenin.

The molecule most likely forms heterotrimers.
