LATS1(large tumor suppressor kinase 1),癌症关联基因,基因ID:9113,该基因编码的蛋白是一种推测的丝氨酸/苏氨酸激酶,在有丝分裂早期定位于有丝分裂器并与细胞周期调控因子cdc2激酶复合。蛋白质以细胞周期依赖的方式磷酸化,晚期前期磷酸化通过中期保持。蛋白的n-末端区域与cdc2结合形成复合物,显示h1组蛋白激酶活性降低,表明cdc2/cyclin a的负调节作用。此外,c-末端激酶区域与自身的n-末端区域结合,通过分子内结合干扰复合物的形成,提示潜在的负调节作用。生化和遗传数据表明,它是一种肿瘤抑制因子。这一点得到了基因敲除小鼠研究的支持,研究表明,小鼠体内存在软组织肉瘤、卵巢基质细胞瘤以及对致癌治疗的高度敏感性。[由RefSeq提供,2017年4月]The protein encoded by this gene is a putative serine/threonine kinase that localizes to the mitotic apparatus and complexes with cell cycle controller CDC2 kinase in early mitosis. The protein is phosphorylated in a cell-cycle dependent manner, with late prophase phosphorylation remaining through metaphase. The N-terminal region of the protein binds CDC2 to form a complex showing reduced H1 histone kinase activity, indicating a role as a negative regulator of CDC2/cyclin A. In addition, the C-terminal kinase domain binds to its own N-terminal region, suggesting potential negative regulation 。
