What is the molecular weight of HDAC3? Is HDAC3 post-translationally modified?

The molecular weight of HDAC3 is 49 kDa but HDAC3 can form homodimers and homotrimers in cells (PMID: 11779848). HDAC3 can be phosphorylated at S424 residue by protein kinase CK2, which regulates HDAC3 activity (PMID: 15805470).

 What is the subcellular localization of HDAC3?

Unlike other class I HDACs, HDAC3 actively shuttles between the nucleus and cytoplasm (PMID: 11779848). Additionally, HDAC3 can be present at the plasma membrane, where it associates with c-Src (PMID: 16532030).

 What is the tissue expression pattern of HDAC3?

Like other class I HDACs, HDAC3 is ubiquitously expressed (PMID: 9346952).

 What is the mechanism of HDAC3 in regulating gene expression?

Unlike other histone deacetylates, it exists in a complex with two proteins - nuclear receptor co-repressor (N-CoR) and silencing mediator for retinoid and thyroid receptors (SMRT) - and therefore acts as a mediator of the repression function of unliganded nuclear hormone receptors (PMID: 10809664). N-CoR and SMRT play an active role in the recruitment of HDAC3 to binding sites as well as directly regulating HDAC3 activity. Additionally, HDAC3 targets growth-regulated genes.
