1CTR - PubMed Abstract: 
The crystal structure of calmodulin (CaM) bound to trifluoperazine (TFP) has been determined and refined to a resolution of 2.45 A. Only one TFP is bound to CaM, but that is sufficient to cause distortion of the central alpha-helix and juxtaposition of the N- and C-terminal domains similar to that seen in CaM-polypeptide complexes ...
