HDAC3基因编码功能及结构描述
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。它具有组蛋白脱乙酰酶活性，与启动子结合时抑制转录。它可能通过与锌指转录因子yy1结合参与转录调控。这种蛋白还可以下调p53的功能，从而调节细胞的生长和凋亡。该基因被认为是一种潜在的肿瘤抑制基因。[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 the histone deacetylase/acuc/apha family. It has histone deacetylase activity and represses transcription when tethered to a promoter. It may participate in the regulation of transcription through its binding with the zinc-finger transcription factor YY1. This protein can also down-regulate p53 function and thus modulate cell growth and apoptosis. This gene is regarded as a potential tumor suppressor gene. [provided by RefSeq, Jul 2008]
