Differential screening-selected gene aberrative in neuroblastoma (DAN) encodes a protein which possesses metal binding motifs. Glutathione S-transferase DAN fusion protein had an ability to bind to Ni(2+)-immobilized affinity resin. Truncation of the C-terminal region including a (HX)n repeat of DAN caused a loss of binding ability to the affinity resin, suggesting that this region is essential for Ni(2+)-binding. DAN produced in cultured rat cells also had an affinity for Ni2+. Cross-linking experiments demonstrated that the C-terminal region might function as a protein-protein interacting domain.
神经母细胞瘤差异筛选选择的基因异常(DAN)编码一种具有金属结合基序的蛋白质。谷胱甘肽S-转移酶DAN融合蛋白具有与固定化镍(2+)亲和树脂结合的能力。DAN C末端区域的截断,包括(HX)n重复序列,导致与亲和树脂结合能力丧失,表明该区域对于镍(2+)结合至关重要。在培养的大鼠细胞中产生的DAN对镍2+也具有亲和力。交联实验表明,C末端区域可能作为蛋白质-蛋白质相互作用结构域发挥作用。
