表型提示
MGI:107365Embryos homozygous for a targeted null mutation die prior to E7.5. In culture, mutant blastocysts are viable up to 2 days but show subsequent apoptosis of the inner cell mass. Mutant cells exhibit major chromosome condensation and segregation defects as well as gross defects in nuclear organization.
UBE2I,也称为Ubiquitin-conjugating enzyme E2I,是一种重要的蛋白质,属于泛素结合酶E2家族。泛素-蛋白酶体系统(UPS)是细胞内重要的蛋白质降解途径,参与调控细胞周期、信号传导、基因表达和蛋白质稳定性等多种生物学过程。UBE2I作为UPS系统的组成部分,通过催化泛素与底物蛋白的结合,参与调控蛋白质的降解和细胞内信号传导。UBE2I在多种细胞过程中发挥重要作用,包括细胞周期、细胞分化和发育等。

UBE2I的表达与多种疾病的发生和发展密切相关。例如,在男性不育症中,UBE2I基因的变异与精子活力低下(asthenozoospermia)的发生有关[1]。此外,UBE2I在脂肪细胞中的缺失会导致脂肪萎缩(lipoatrophy),进而影响能量平衡和代谢稳态[2]。在脑肿瘤中,UBE2I的表达与不同亚型的肿瘤发生和发展有关[3]。此外,UBE2I在肾细胞癌(ccRCC)中作为新型生物标志物,其表达与患者的生存率相关[4]。UBE2I还参与了肝癌的免疫抑制,并通过调节NF-κB信号通路和PD-L1的表达影响肿瘤细胞的免疫逃逸[5]。此外,UBE2I在食管癌中作为一种肿瘤抑制基因,其变异基因UBE2I-v5的转染可以增加肿瘤细胞对抗癌药物的敏感性[6]。在肝细胞癌(HCC)中,UBE2I的表达与肿瘤的转移和预后不良相关[7]。在骨关节炎(OA)中,UBE2I通过促进SUMO化修饰调节hnRNPA2B1的核转位[8]。此外,UBE2I在多囊卵巢综合征(PCOS)和子宫内膜癌(EC)中也具有重要作用[9]。UBE2I的克隆、表达和定位研究显示,UBE2I在多种人类组织中均有表达,并定位于16号染色体[10]。

综上所述,UBE2I作为一种重要的泛素结合酶E2,参与调控细胞内蛋白质的降解和信号传导,影响细胞周期、细胞分化和发育等多种生物学过程。UBE2I的表达与多种疾病的发生和发展密切相关,包括男性不育症、脂肪萎缩、脑肿瘤、肾细胞癌、肝癌、食管癌、骨关节炎、多囊卵巢综合征和子宫内膜癌等。UBE2I的研究有助于深入理解UPS系统的生物学功能和疾病发生机制,为疾病的治疗和预防提供新的思路和策略。
