Histones play a critical role in transcriptional regulation, cell cycle progression, and developmental events. Histone acetylation/deacetylation alters
chromosome structure and affects
transcription factor access to DNA. The protein encoded by this gene belongs to the class II histone deacetylase/acuc/apha family. It possesses
histone deacetylase activity and represses transcription when tethered to a promoter. It coimmunoprecipitates only with HDAC3 family member and might form multicomplex proteins. It also interacts with myocyte enhancer factor-2 (MEF2) proteins, resulting in repression of MEF2-dependent genes. This gene is thought to be associated with colon cancer. Two transcript variants encoding different isoforms have been found for this gene. HDAC5 is involved in
memory consolidation and suggests that development of more selective
HDAC inhibitors for the treatment of
Alzheimer's disease should avoid targeting HDAC5. Its function can be effectively examined by siRNA knockdown based on an independent validation. HDAC5 overexpression in
urothelial carcinoma cell lines inhibits long-term proliferation but can promote epithelial-to-mesenchymal transition (
EMT) == Interactions ==
