Function
Histone deacetylase (HDAC) catalyzes the removal of acetyl group from ε-N-acetyl lysine in histones[1]. HDAC contains Zn. DNA expression is regulated by acetylation and de-acetylation. SAHA is a common inhibitor of HDAC. HDAC are classified according to their domain organization into 4 classes.
- HDAC class I are homologous to yeast Rpd3.
- HDAC class II are homologous to yeast HdaI.
- HDAC class III called sirtuin - Silent Information Regulator) (SIRT) are NAD-dependent HDAC [2].
For additional details see
- Understanding of the Recruitment of HDACs by MEF2, Based on Their Structure
- Transcription and RNA Processing.
Relevance
HDAC inhibitors are used in cancer therapy[3]. Sirtuins play a role in cancer, metabolic activity and neurodegenerative diseases[4].
