From Histone Modification To Gene Repression: Epigenetic Regulation By Holocarboxylase Synthetase-Containing Repression Complex And Fad-Dependent Lysine Specific Demethylase, Dandan Liu
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Histones undergo different types of post-translational modifications that have been linked to a variety of biological processes and disease states. Histone acetylation and methylation are well characterized modifications with respect to regulation of chromatin structure and transcription. Histone acetylation, regulated by histone acetyltransferases (HATs) and histone deacetylases (HDACs), is linked with gene activation. Here we introduce a novel paradigm suggesting that holocarboxylase synthetase (HLCS), the sole biotin protein ligase in the human genome, recruits nuclear receptor corepressor (N-CoR) and HDAC1 to chromatin, thereby contributing toward the removal of lysine (K)-9 acetylated histone H3 (H3K9ac) gene activation marks and the repression …
