同源结构域相互作用蛋白激酶2(HIPK2)是定位于细胞核内的丝/苏氨酸蛋白激酶家族成员之一,不仅与晚期胚胎发生、神经组织、视网膜及肌肉组织发育等密切相关,还参与调控肿瘤信号传导、下调癌基因表达、诱导肿瘤细胞凋亡和抑制肿瘤血管新生.HIPK2对肿瘤信号传导通路的调节主要与P53信号、Wnt/β-catenin通路及缺氧等密切相关.
Homeodomain-interacting protein kinase 2(HIPK2)is a member of a member of the serine/threonine protein kinase family which localized in the mucleus.It is not only involved in advanced stage embryogenesis,development of nerve tissue,retina and muscular tissue,but also takes part in regulation of tumor signaling transduction,down-modulated expression of oncogene,induced apoptosis of tumor cells,and inhibited angiogeuesis of tumor.The regulation of HIPK2 in tumor signaling transduction pathway is associated with P53 signaling,Wnt/β-catenin pathway and hypoxia.
