混合谱系激酶(MLK)4或MLK 4是有丝分裂原活化蛋白激酶(MAP 3 Ks)MLK家族的成员。典型地,MAP 3 K的功能是激活促分裂原活化蛋白激酶(MAPK)信号通路并调节不同的细胞应答。然而,在这里,我们报告MLK 4 β,不像其他MLK,负调节MAPK,p38,c-Jun N-末端激酶和细胞外信号调节激酶,以及MAP 2Ks,MEK 3和6的活性。我们的结果表明MLK 4 β抑制山梨醇和肿瘤坏死因子诱导的p38激活。此外,MLK 4 β在HCT 116细胞中与另一个MLK家族成员MLK 3相互作用。MLK 4 β的外源性表达抑制了MLK 3的活化,也阻断了SKOV 3卵巢癌细胞中基质金属蛋白酶-9明胶酶的活性和侵袭。总的来说,我们的数据确定MLK 4 β是MLK 3活化、MAPK信号传导和细胞侵袭的新型抑制剂。
Mixed lineage kinase (MLK) 4, or MLK4, is a member of the MLK family of mitogen-activated protein kinase kinase kinases (MAP3Ks). Typically, MAP3Ks function to activate the mitogen-activated protein kinase (MAPK)-signaling pathways and regulate different cellular responses. However, here we report that MLK4β, unlike the other MLKs, negatively regulates the activities of the MAPKs, p38, c-Jun N-terminal kinase and extracellular signal-regulated kinase, and the MAP2Ks, MEK3 and 6. Our results show that MLK4β inhibits sorbitol- and tumor necrosis factor-induced activation of p38. Furthermore, MLK4β interacts with another MLK family member, MLK3, in HCT116 cells. Exogenous expression of MLK4β inhibits activation of MLK3 and also blocks matrix metalloproteinase-9 gelatinase activity and invasion in SKOV3 ovarian cancer cells. Collectively, our data establish MLK4β as a novel suppressor of MLK3 activation, MAPK signaling and cell invasion.
