Novel mechanism of nuclear receptor corepressor interaction dictated by activation function 2 helix determinants.

abstract：:Circadian clock genes are regulated through a transcriptional-translational feedback loop. Alterations of the chromatin structure by histone acetyltransferases and histone deacetylases (HDACs) are commonly implicated in the regulation of gene transcription. However, little is known about the transcriptional regulation...
