一般描述
泛素是球形蛋白,由 76 个氨基酸组成,表面具有赖氨酸残基。它的分子量为8565 Da。[1]在聚泛素—蛋白质结合物形成的过程中,N末端组氨酸标记的泛素可以代替天然的泛素。组氨酸标签可用于在Ni(II)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组氨酸标签抗体检测结合物。
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.[2]

应用
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。[3]
生化/生理作用
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.[10]

Plants can cope with adverse environmental conditions through the activation of stress response signalling pathways, in which the proteasome seems to play an important role. However, the mechanisms underlying the proteasome-mediated stress response in rice are still not fully understood.
