一般說明

泛素是球形蛋白,由 76 个氨基酸组成,表面具有赖氨酸残基。分子量为 8565 Da。
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

人泛素可作为研究水稻 E3-Ubiquitin 连接酶的分离、鉴定及 OsHOS1 基因在冷应激反应调控中的作用的供试化合物。
泛素(人)可用于:
  • 作为底物,用于 体外 泛素化测定
  • 作为底物,用于ADP-核糖基化和泛素化测定
  • 向新鲜血液补充 64 ng内源性泛素,用于实验分组,研究其对癌症预后的临床潜在影响

生化/生理作用

泛素对真核细胞发挥正常功能起关键作用。参与免疫系统发育和免疫系统功能正常运行。此外,此免疫亲和蛋白还参与调节免疫稳态。泛素肽片段(U50-59)能够阻断细胞免疫和体液免疫。
泛素是存在于真核生物组织中的一种小分子调节蛋白。外源性泛素可以刺激许多细胞系凋亡。人乳头状瘤病毒-16 的 E7 蛋白通过泛素-蛋白酶体途径刺激视网膜母细胞瘤蛋白降解。
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.
