The crystal structure of calcineurin B homologous proein 1 (CHP1)

The structure was published by Naoe, Y., Arita, K., Hashimoto, H., Kanazawa, H., Sato, M., and Shimizu, T., in 2005 in a paper entitled "Structural characterization of calcineurin B homologous protein 1" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 2005.

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

This PDB entry contains multiple copies of the structure of Calcium-binding protein p22.

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.
