一般說明
DKK-1(dickkopf WNT信号转导途径抑制剂1)是DKK蛋白家族的成员,该家族还包括DKK-2、DKK-3和DKK-4。 在人293细胞中表达的重组人DKK-1是一种含有235个氨基酸残基的35-40kDa的糖蛋白。
Research Area: Cell Signaling
The Dkk-1 gene is a prototype member of a newly identified gene family that encodes secreted glycoproteins responsible for regulating cell fate and neural patterning during embryonic development.

應用
人DKK-1已被用于人脂肪来源的基质/干细胞的预培养,从而进一步在神经元分化混合培养基中进行培养。 它还被用于将诱导的多能干细胞分化成光感受器祖细胞。
生化/生理作用
DKK-1(dickkopf WNT信号转导途径抑制剂1)最初被鉴定为非洲爪蟾头部形成分子,其表现为Wnt信号转导的拮抗剂。 随后的研究表明,DKK-1可通过与LDL受体相关蛋白5和6(LRP5和LRP6)形成抑制性复合物( Wnt/β-连环蛋白信号系统的必需成分),在 Wnt/β-连环蛋白信号通路中发挥重要的调节作用。 有人提出,通过抑制 Wnt/β-连环蛋白信号转导(其对于脊椎动物的后部模式是必不可少的),DKK-1可促进前部发育。这一概念得到以下发现的支持:缺乏DKK-1表达的小鼠无法形成头部并且在胚胎发生期间死亡。 在膀胱癌中,DKK-1在血清中过表达并且可能与肿瘤进展相关。 它还与多发性骨髓瘤相关并影响骨形成。 血清DKK1水平的变化与类风湿性关节炎的炎症有关。 在发育、肿瘤发生和炎症的过程中,DKK1可增强血管生成。
The human Dkk-1 (hDkk-1) gene, a transcriptional target of the p53 tumor suppressor, encodes a potent inhibitor of the Wnt signaling pathway and plays a role in the spatial patterning and morphogenesis of the mammalian central nervous system. As a pro-apoptotic gene, hDkk-1 suggests significant involvement in connecting the oncogenic Wnt pathway with the p53 tumor suppressor pathway.
