产品介绍 : The 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes, a 20S core and a 19S regulator. The 20S core is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. The 19S regulator is composed of a base, which contains 6 ATPase subunits and 2 non-ATPase subunits, and a lid, which contains up to 10 non-ATPase subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. This gene encodes a member of the proteasome subunit S9 family that functions as a non-ATPase subunit of the 19S regulator and is phosphorylated by AMP-activated protein kinase. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Jul 2012]
Function:
Component of the lid subcomplex of the 26S proteasome, a multiprotein complex involved in the ATP-dependent degradation of ubiquitinated proteins. In the complex, PSMD11 is required for proteasome assembly. Plays a key role in increased proteasome activity in embryonic stem cells (ESCs): its high expression in ESCs promotes enhanced assembly of the 26S proteasome, followed by higher proteasome activity.
Subcellular Location:
Nucleus. Cytoplasm > cytosol.
Tissue Specificity:
Highly expressed in embryonic stem cells (ESCs). Expression decreases as ESCs differentiate.
Post-translational modifications:
Phosphorylated by AMPK.
Similarity:
Belongs to the proteasome subunit S9 family.
Contains 1 PCI domain.
SWISS:
O00231
Gene ID:
5717

文献和实验【求助】P53的翻译后修饰都有哪些？ 怎样验证其修饰后与靶标启动子的结合活性的变化？
可通过p53结合蛋白PRMT1和CARM1（辅助活化因子相关的精氨酸甲基转移酶）相互作用获得。当靶基因的转录激活不再需要p53时去乙酰化作用可以作为一种快速的调节机制来抑制p53的功能。 泛素化修饰 正常细胞中降解是消除p53功能的唯一机制，这种降解部分是由泛素-26S蛋白酶体系统完成的（其它途径是非泛素依赖性的）。泛素是一种高度保守的蛋白质，靶向作用于底物蛋白，使其被26S蛋白酶体降解成多肽。泛素连接酶实现了泛素化修饰的最后一步，这些酶显示出一种高水平的靶向特异性。正常
蛋白质组是动态的，随着大量刺激的变化而变化，翻译后修饰常用于调节细胞活性。PTM 发生在不同的氨基酸侧链或肽键上，它们通常由酶活性介导。事实上，据估计，5% 的蛋白质组包含 200 多种类型翻译后修饰的酶。这些酶包括激酶、磷酸酶、转移酶和连接酶，它们在氨基酸侧链上添加或移除功能组、蛋白质、脂质或糖；以及蛋白酶，它们切割肽键以移除特定序列或调节亚基。许多蛋白质也可以利用自催化结构域，如自激酶和自蛋白分解结构域进行自我修饰。翻译后修饰可以发生在蛋白质生命周期的任何阶段。例如，许多蛋白质在翻译完成后不久就被修饰
