一般說明
泛素是一种高度保守的球蛋白，表面有赖氨酸。C末端包含Leu-Arg-Gly-Gly结构基序。
Research Area: CANCER
Ubiquitin is a highly conserved protein composed of 76 amino acids, and it is expressed universally in all eukaryotes, ranging from yeast to humans.

應用
N端FLAG标签泛素可取代泛素，用于形成多聚泛素-蛋白结合物。FLAG标签可用于在抗-FLAG亲和柱上分离和富集蛋白结合物，以及在蛋白免疫印迹法中通过抗-FLAG抗体检测结合物。
人泛素可用作质谱的标准品。
人类泛素已用于酵母增殖细胞核抗原(PCNA)的单泛素化 和有丝分裂阻滞1（Dma1）缺陷的体外泛素化测定
生化／生理作用
泛素是存在于真核细胞组织中的小调节蛋白。外源性泛素可刺激许多细胞系中的细胞凋亡。 人乳头瘤病毒-16的E7蛋白可通过泛素-蛋白酶体途径刺激视网膜母细胞瘤蛋白的降解。
泛素通过其C末端甘氨酸残基的ε-氨基与蛋白质的赖氨酸残基相互作用。与泛素相互作用的蛋白质通过一个三步过程进行单泛素化（mono-ubiquitination）或多单泛素化（multi-mono-ubiquitination）。泛素化调节细胞内运输和蛋白质降解，并且该途径的失衡与疾病有关。
Ubiquitin-mediated proteolysis plays an important role in several basic cellular processes including regulation of cell cycle and division, differentiation and development, modulation of cell-surface receptors, the secretory pathway (protein transport), morphogenesis of neuronal networks, transcriptional regulation and signal transduction, transcriptional silencing, DNA repair, long-term memory, and circadian rhythms.

Protein ubiquitination and protein phosphorylation are two fundamental regulatory post-translational modifications controlling intracellular signalling events. However, the ubiquitin system is vastly more complex compared with phosphorylation. This is due to the ability of ubiquitin to form polymers, i.e. ubiquitin chains

Ubiquitin is a small globular protein that has a considerable number of lysine residues on its surface. This results in a high surface entropy that precludes the formation of crystal-packing interactions. To date, only a few structures of the native
