产品介绍
HDAC6是一种比较独特的组蛋白去乙酰化酶,含有两个功能上相互独立的HDAC催化结构域。HDAC6可以去乙酰化组蛋白并抑制相关基因转录。
HDAC6可以和微管(microtuble)结合,可以去乙酰化tubulin,Hsp90和cortactin等。目前发现大量的蛋白可以被乙酰化修饰,因此HDAC等乙酰化修饰酶被认为在基因转录调控、信号转导、生长发育、分化凋亡、代谢性疾病和肿瘤等多种生理病理过程中发挥重要作用。HDAC的抑制剂目前被认为是很有前景的肿瘤治疗药物。
内源性HDAC6主要定位于细胞浆,与微管相结合并且是一个微管蛋白去乙酰化酶。HDAC6含有一个锌指结构域,该结构域可能和泛素化降解的调节有关。HDAC6可以和DHAC11相互作用。
背景资料
HDAC6 is a member of the class II mammalian histone deacetylases. Human HDAC6 is composed of 1215 amino acid residues. It possesses two separate putative catalytic domains. Both catalytic domains are fully functional HDACs and contribute independently to the overall activity of HDAC6 protein. A very potent NES is present at the amino-terminus of HDAC6, which was found to play an important role in regulating the shuttling of HDAC6 protein between cytoplasm and nucleus. The shuttling process may be a critical regulatory mechanism of HDAC6 function. The expression of HDAC6 is tightly linked to the state of cell differentiation. HDAC6 may participate in coordinating expression of a group of genes involved in the remodelling of chromatin during cell differentiation.
蛋白名
Histone deacetylase 6
亚基
Interacts with CBFA2T3, HDAC11 and SIRT2. Interacts with F-actin. Interacts with BBIP10. Under proteasome impairment conditions, interacts with UBD via its histone deacetylase 1 and UBP-type zinc-finger regions. Interacts with CYLD. Interacts with ZMYND15 (By similarity). Interacts with DDIT3/CHOP.
亚细胞定位
Nucleus. Cytoplasm. Note=It is mainly cytoplasmic, where it is associated with microtubules.
翻译后修饰
Phosphorylated by AURKA.
Ubiquitinated. Its polyubiquitination however does not lead to its degradation.
Sumoylated in vitro.
相似性
Belongs to the histone deacetylase family. HD type 2 subfamily.
Contains 1 UBP-type zinc finger.
功能
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. Plays a central role in microtubule-dependent cell motility via deacetylation of tubulin.
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.
