4a4c Summary


Structure of phosphoTyr371-c-Cbl-UbcH5B-ZAP-70 complex

There is a Quite Interesting Protein Structure article for this entry.

The structure was published by Dou, H., Buetow, L., Hock, A., Sibbet, G.J., Vousden, K.H., and Huang, D.T., in 2012 in a paper entitled "Structural Basis for Autoinhibition and Phosphorylation-Dependent Activation of C-Cbl" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.704 Å and deposited in 2011.

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

This PDB entry contains a complex of 3 biomacromolecules, namely E3 UBIQUITIN-PROTEIN LIGASE CBL, TYROSINE-PROTEIN KINASE ZAP-70, and UBIQUITIN-CONJUGATING ENZYME E2 D2.

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 most likely forms heterotrimers.
