title: Thyroid hormone receptor-containing fragment released from chromatin by deoxyribonuclease I and micrococcal nuclease.
abstract: Limited deoxyribonuclease I and micrococcal nuclease digestion of hepatic nuclei from euthyroid rats injected with 125I-labeled triiodothyronine ([125I]T3)  releases a discrete [125I]T3-labeled chromatin fragment (5.8S) which is larger than the T3 receptor (3.5S). These results suggest the T3 receptor is associated with a restricted fraction of hepatic chromatin that has a nuclease sensitivity characteristic of transcriptionally active chromatin.
