HDAC6（histone deacetylase 6），癌症关联基因，基因ID：10013，组蛋白在转录调控、细胞周期进展和发育事件中起着关键作用。组蛋白乙酰化/去乙酰化改变染色体结构并影响转录因子对dna的获取。该基因编码的蛋白属于组蛋白去乙酰化酶/acuc/apha家族的Ⅱ类。它包含两个催化结构域的内部复制，这两个催化结构域看起来相互独立。该蛋白具有组蛋白脱乙酰酶活性并抑制转录。[由RefSeq提供，2008年7月]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.
