STRUCTURES OF THE APO AND CALCIUM TROPONIN-C REGULATORY DOMAINS: THE MUSCLE CONTRACTION SWITCH

The structure was published by Gagne, S.M., Tsuda, S., Li, M.X., Smillie, L.B., and Sykes, B.D., in 1995 in a paper entitled "Structures of the troponin C regulatory domains in the apo and calcium-saturated states." (abstract).

The structure was determined using NMR spectroscopy and deposited in 1995.

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

The PDB entry contains the structure of TROPONIN-C (APO). This molecule has the UniProt identifier P02588 (TNNC2_CHICK)search. The sample contained 90 residues which is < 90% of the natural sequence. Out of 90 residues 90 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
