Previous GeneCards Identifiers for HDAC6 Gene
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 class II of the histone deacetylase/acuc/apha family. It contains an internal duplication of two catalytic domains which appear to function independently of each other. This protein possesses histone deacetylase activity and represses transcription.

GeneCards Summary for HDAC6 Gene
HDAC6 (Histone Deacetylase 6) is a Protein Coding gene. Diseases associated with HDAC6 include Chondrodysplasia With Platyspondyly, Distinctive Brachydactyly, Hydrocephaly, And Microphthalmia and Alexander Disease. Among its related pathways are Notch signaling pathway (KEGG) and Organelle biogenesis and maintenance. Gene Ontology (GO) annotations related to this gene include enzyme binding and ubiquitin protein ligase binding. An important paralog of this gene is HDAC4.
UniProtKB/Swiss-Prot for HDAC6 Gene
Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes (By similarity). Plays a central role in microtubule-dependent cell motility via deacetylation of tubulin. Involved in the MTA1-mediated epigenetic regulation of ESR1 expression in breast cancer.
In addition to its protein deacetylase activity, plays a key role in the degradation of misfolded proteins: when misfolded proteins are too abundant to be degraded by the chaperone refolding system and the ubiquitin-proteasome, mediates the transport of misfolded proteins to a cytoplasmic juxtanuclear structure called aggresome. Probably acts as an adapter that recognizes polyubiquitinated misfolded proteins and target them to the aggresome, facilitating their clearance by autophagy.
Histone deacetylases (HDACs) are a group of enzymes closely related to sirtuins. They catalyze acetyl group removal from lysine residues in histones and non-histone proteins, causing transcriptional repression. HDACs are usually components of multiprotein complexes.
