Tandem SH2 domains of ZAP-70 with 19-mer zeta1 peptide

The structure was published by Hatada, M.H., Lu, X., Laird, E.R., et al., Phillips, T.B., Ram, M.K., and Theriault, K., in 1995 in a paper entitled "Molecular basis for the interaction of ZAP-70 with the T-cell receptor" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2007.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Tyrosine-protein kinase ZAP-70 and T-cell surface glycoprotein CD3 zeta chain.

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 heterodimers.
