4hcu Summary


Crystal structure of ITK in complext with compound 40

The structure was published by Zapf, C.W., Gerstenberger, B.S., Xing, L., et al., Czerwinski, R.M., Seth, N., and Medley, Q.G., in 2012 in a paper entitled "Covalent inhibitors of interleukin-2 inducible T cell kinase (itk) with nanomolar potency in a whole-blood assay." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.43 Å and deposited in 2012.

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

The PDB entry contains the structure of Tyrosine-protein kinase ITK/TSK. This molecule has the UniProt identifier Q08881 (ITK_HUMAN)search. The sample contained 269 residues which is < 90% of the natural sequence. Out of 269 residues 263 were observed and are deposited in the PDB.

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 is most likely monomeric.
