表型提示
MGI:1341217Homozygous null mutants die at the peri-implantation stage. Mutants exhibit selective apoptosis of the inner cell mass but not of trophoblastic cells. Moreover, the trophoblastic cells fail to enter the S phase of the endoreduplication cycle.
Uba3,全称为Ubiquitin-activating enzyme E1, also known as UBA3, 是NEDD8(neural precursor cell expressed developmentally down-regulated protein 8)激活酶E1的唯一催化亚基。NEDD8是一种类泛素蛋白,可以通过其羧基端的甘氨酸残基共价连接到靶蛋白上,类似于泛素化过程。Uba3在NEDD8的激活和转移过程中起着关键作用,NEDD8的修饰在多种生物学过程中发挥重要作用,包括细胞周期调控、信号转导、蛋白质降解和免疫反应等[8]。

Uba3在多种癌症中发挥重要作用。例如,在成人T细胞白血病/淋巴瘤(ATLL)中,Uba3与NEDD8、NAE1和CUL3等基因一起负调控PD-L1的表达,而STAT3则正调控PD-L1的表达[1]。在肝内胆管癌(ICC)中,Uba3通过影响ANXA2通过MAPK信号通路促进ICC的发生和转移[3]。在肺腺癌(LUAD)中,Uba3的表达水平升高,并且Uba3依赖的neddylation途径与免疫抑制细胞群的浸润有关,包括肿瘤相关巨噬细胞(TAMs)、浆细胞样树突状细胞(pDCs)、Th2细胞和T调节细胞(Tregs),这可能有助于肿瘤免疫逃逸和恶性进展[4]。在乳腺癌中,PTEN蛋白水平的降低会影响MLN4924(Pevonedistat)的抗肿瘤作用,因为PTEN是MLN4924抑制肿瘤生长的关键因素[5]。

除了在癌症中的作用外,Uba3还与其他疾病有关。例如,在黑腹果蝇中,Uba3的突变会导致幼虫/胚胎死亡,并且Uba3 O.2.2突变会导致头部发育减少和眼组织变暗[2]。在3p13缺失综合征中,Uba3的缺失可能会导致面部畸形、心脏畸形、发育迟缓、自闭症谱系障碍、癫痫和鼻后孔闭锁等临床表现[6]。在脊髓损伤后,Uba3与Sumo1和Pik3ca一起被鉴定为与运动神经元兴奋性相关的关键基因[7]。

综上所述,Uba3是一种重要的NEDD8激活酶E1的催化亚基,参与NEDD8的修饰过程,在多种生物学过程中发挥重要作用。Uba3在癌症、发育、免疫和其他疾病中发挥重要作用,因此Uba3可能成为治疗这些疾病的新靶点。
