[Hydrocortisone-receptor complex binding with various nonhistone protein groups].

Complexes containing DNA and various groups of non-histone proteins were isolated from rat liver cells. Deproteinized DNA was bound with the hydrocortisone-receptor complex at the highest rate in vitro. Non-histone proteins from the chromatin fraction did not bind with the hormone-receptor complex. Unsaturability of DNA in reaction with the complex appears to indicate the low specificity of binding.
