Structure of a c-Kit Kinase Product Complex

The structure was published by Mol, C.D., Lim, K.B., Sridhar, V., et al., Kassel, D.B., Cronin, C.N., and McRee, D.E., in 2003 in a paper entitled "Structure of a c-Kit Product Complex Reveals the Basis for Kinase Transactivation." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.9 Å and deposited in 2003.

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

This PDB entry contains multiple copies of the structure of c-kit protein.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
