3ob2 Summary


Crystal structure of c-Cbl TKB domain in complex with double phosphorylated EGFR peptide

The structure was published by Sun, Q., Jackson, R.A., Ng, C., Guy, G.R., and Sivaraman, J., in 2010 in a paper entitled "Additional serine/threonine phosphorylation reduces binding affinity but preserves interface topography of substrate proteins to the c-Cbl TKB domain" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2010.

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

This PDB entry contains a complex of 2 biomacromolecules, namely 12-meric peptide from Epidermal growth factor receptor and E3 ubiquitin-protein ligase CBL.

The molecule most likely forms heterodimers.
