我们报道小鼠Hox-1.3同源结构域蛋白是一种能够结合特定DNA序列的核磷酸化蛋白。dna酶I保护Hox-1.3基因启动子区域与Hox-1.3蛋白在转录开始上游144bp处鉴定了一个结合位点。磷酸化和非磷酸化形式都以序列特异性的方式直接结合DNA。电泳迁移率转移试验是用一组合成的寡核苷酸进行的,这些寡核苷酸代表了Hox-1.3基因的DNase i保护区域或部分同源序列,这些序列存在于其他特征病毒、酵母和哺乳动物基因的启动子区域。从结果中,我们推导出CPyPyNATTAT/GPy的一致绑定基序。核心ATTA序列的碱基替换严重减少或消除了结合。在SV40增强子中,Hox-1.3结合基序与八聚体(Octa2)和反活化蛋白-1 (AP-1)结合位点重叠。在腺病毒-2的DNA复制起源中,Hox-1.3结合基序也与核因子III (NF-III)八聚体基序重叠。dna结合位点之间的重叠表明,某些顺式元件赋予的调控可能被这些不同的因素整合在一起。
We report that the murine Hox-1.3 homeo domain protein is a nuclear phosphoprotein capable of binding to specific DNA sequences. DNase I protection of the Hox-1.3 gene promoter region with the Hox-1.3 protein identifies a binding site 144 bp upstream from the start of transcription. Both phosphorylated and nonphosphorylated forms bind DNA directly in a sequence-specific manner. Electrophoretic mobility shift assays were performed with a set of synthetic oligonucleotides representing either the DNase I-protected region of the Hox-1.3 gene or partially homologous sequences present in promoter regions of other characterized viral, yeast, and mammalian genes. From the results, we deduce a consensus binding motif of CPyPyNATTAT/GPy. Base substitutions in the core ATTA sequence severely reduce or abolish binding. In the SV40 enhancer, the Hox-1.3 binding motif overlaps both the octamer (Octa2) and the transactivator protein-1 (AP-1) binding sites. The Hox-1.3 binding motif also overlaps the nuclear factor III (NF-III) octamer motif in the adenovirus-2 origin of DNA replication. Overlap among DNA-binding sites suggests that regulation imparted by certain cis-elements may be integrated by these different factors.
