We report cDNA sequence, the complete derived aa sequence, and a predicted secondary structure of the chick hsp 90, a protein which has been found to form complexes with steroid hormone receptors. The modelling of the most negatively charged "region A" indicates that the alpha-helices of this portion of hsp 90 mimick DNA configuration. We propose that this region can, in absence of hormone, interact with and cap the positively charged DNA-binding domain of steroid receptors.
