probe the function of the PDZ domain from human AF6 (ALL1‐fused gene from chromosome 6), which is an essential component of cell–cell junctions. These compounds bind to AF6 PDZ with substantially higher affinity than the peptide (Ile‐Gln‐Ser‐Val‐Glu‐Val) derived from its natural ligand, EphB2. In intact cells, the compounds inhibit the AF6–Bcr interaction and interfere with epidermal growth factor (EGF)‐dependent
PDZ(PSD-95,Dlg,ZO-1)域是无处不在的相互作用模块,涉及许多细胞信号转导途径。干扰PDZ介导的蛋白质间相互作用在疾病相关的信号传导过程中具有重要意义。因此,PDZ域已成为抑制剂设计和长期药物开发的潜在靶点。在这里,我们报道了小分子的发展,以探测人AF6(来自6号染色体的ALL1融合基因)的PDZ结构域的功能,这是细胞间连接的重要组成部分。这些化合物与AF6 PDZ的结合亲和力比其天然配体EphB2衍生的肽(Ile-Gln-Ser-Val-Glu-Val)高得多。在完整的细胞中
