MAPK14（mitogen-activated protein kinase 14），癌症关联基因，基因ID：1432，这个基因编码的蛋白质是MAP激酶家族的一员。MAP激酶作为多种生化信号的整合点，参与细胞增殖、分化、转录调控和发育等多种过程。这种激酶被各种环境压力和促炎细胞因子激活。活化需要MAP激酶激酶（MKKS）的磷酸化，或MAP3K7IP1/TAB1蛋白与该激酶相互作用引发的自身磷酸化。该激酶的底物包括转录调节因子atf2、mef2c和max、细胞周期调节因子cdc25b和肿瘤抑制因子p53，这表明该激酶在应激相关转录和细胞周期调节以及遗传毒性应激反应中的作用。报道了四种编码不同亚型基因的选择性剪接转录变体。[由RefSeq提供，2008年7月]The protein encoded by this gene is a member of the MAP kinase family. MAP kinases act as an integration point for multiple biochemical signals， and are involved in a wide variety of cellular processes such as proliferation， differentiation， transcription regulation and development. This kinase is activated by various environmental stresses and proinflammatory cytokines. The activation requires its phosphorylation by MAP kinase kinases (MKKs)， or its autophosphorylation triggered by the interaction of MAP3K7IP1/TAB1 protein with this kinase. The substrates of this kinase include transcription regulator ATF2， 。
