HDAC6: Tumor Progression and Beyond.

Histone Deacetylase 6 (HDAC6) is an intriguing therapeutic target in cancer re-search, distinguished as the only HDAC family member predominantly located in the cyto-plasm. HDAC6 features two catalytic domains and a unique ubiquitin-binding domain, which sets it apart from other HDACs. Beyond its role in histone deacetylation, HDAC6 targets vari-ous nonhistone substrates, such as α-tubulin, cortactin, Heat Shock Protein 90 (HSP90), and Heat Shock Factor 1 (HSF1).
