FUBP1(far upstream element binding protein 1),癌症关联基因,基因ID:8880,该基因编码的蛋白质是一种单链dna结合蛋白,与多种dna元素结合,包括c-myc上游的远上游元素(fuse)。融合结合发生在非编码链上,对未分化细胞中c-myc的调节具有重要意义。该蛋白包含三个结构域,一个双亲螺旋N-末端结构域,一个DNA结合中心结构域,以及一个包含三个富含酪氨酸基序的C-末端反式激活结构域。n-末端结构域被认为抑制了c-末端结构域的活性。这种蛋白质也被认为与RNA结合,并含有3'-5'螺旋酶活性和DNA-DNA和RNA-RNA双工的体外活性。该基因在恶性肿瘤组织中有异常表达,对神经系统和肺的发育具有重要意义。这种蛋白与病毒rna的结合被认为在一些病毒性疾病中起作用,包括丙型肝炎和手足口病。选择性剪接导致多个转录变体。[由RefSeq提供,2014年12月]The protein encoded by this gene is a single stranded DNA-binding protein that binds to multiple DNA elements, including the far upstream element (FUSE) located upstream of c-myc. Binding to FUSE occurs on the non-coding strand, and is important to the regulation of c-myc in undifferentiated cells. This protein contains three domains, an amphipathic helix N-terminal domain, a DNA-binding central domain, and a C-terminal transactivation domain that contains three tyrosine-rich motifs. The N-terminal domain is thought to repress the activit。
