N-TERMINAL DOMAIN OF CBL IN COMPLEX WITH ITS BINDING SITE ON ZAP-70

The structure was published by Meng, W., Sawasdikosol, S., Burakoff, S.J., and Eck, M.J., in 1999 in a paper entitled "Structure of the amino-terminal domain of Cbl complexed to its binding site on ZAP-70 kinase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 1998.

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

This PDB entry contains a complex of 2 biomacromolecules, namely PROTO-ONCOGENE CBL and ZAP-70.

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 heterohexamers.
