Acceptor proteins in rat androgenic tissue chromatin.

Abstract
Fractionation of chromatin [rat prostate, testis, liver and pancreas] into urea-soluble chromosomal nonhistone proteins (UP), histones (MP) and DNA-associated nonhistone proteins (NP) revealed that the NP fraction from testicular and prostatic chromatin contains organ-specific acceptors for complexes of 5.alpha.-dihydrotestosterone (17.beta.-hydroxy-5.alpha.-androstan-3-one) and its receptor. This acceptor capacity of androgenic tissue chromatin could be transferred to chromatins from non-target tissues with the NP fraction of DNA-associated proteins. Phosphorylation of chromatin its hormone-receptor binding capacity.
