Crystal structure of the N-terminal domain of human cardiac troponin C in complex with trifluoperazine (monoclinic crystal form)

A publication describing this structure is not available. The depositing authors are Takeda, S.search; Igarashi, T.search; Oishi, Y.search; Mori, H.search

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 2004.

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

This PDB entry contains multiple copies of the structure of Troponin C, slow skeletal and cardiac muscles.

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.
