The ubiquitous transcription factor SP1 binds to a GC rich consensus sequence. Here we describe an adaptor molecule that mediates binding of SP1 to a non-cognate DNA site rich in AT. The adaptor is comprised of a Dervan-type hairpin polyamide with high affinity to an AT rich hexamer duplex. It also carries a 27mer DNA that contains the SP1 consensus sequence. The synthesis and purification of the polyamide-DNA
无处不在的转录因子 SP1 与富含 GC 的共有序列结合。在这里,我们描述了一种适配器分子,它介导 SP1 与富含 AT 的非同源 DNA 位点的结合。该接头由对富含 AT 的六聚体双链体具有高亲和力的Dervan型发夹聚酰胺组成。它还携带含有 SP1 共有序列的 27 聚体 DNA。报道了聚酰胺-DNA 偶联物的合成和纯化。Pulldown 实验和蛋白质印迹分析证明了接头介导的 SP1 与六聚体双链体 TTGTTA 的结合。
