p38MAPKSignalingPathway
p38 MAPKs are members of the MAPK family that are activated by a variety of environmental stresses and inflammatory cytokines. Stress signals are delivered to this cascade by members of small GTPases of the Rho family (Rac, Rho, Cdc42). As with other MAPK cascades, the membrane-proximal component is a MAPKKK, typically a MEKK or a mixed lineage kinase (MLK). The MAPKKK phosphorylates and activated MKK3/5, the p38 MAP......阅读全文

p38－MAPK信号通路图
p38 MAPK是1993年由Brewster等人在研究高渗环境对真菌的影响时发现的［8］。以后又发现它也存在于哺乳动物的细胞内，也是MAPKs的亚类之一，其性质与JNK相似，同属应激激活的蛋白激酶。目前已发现p38MAPK有5个异构体，分别为p38α（p38）、p38β1、p38β2、p38γ、p
p38－MAPK蛋白的生理作用
p38丝裂原活化蛋白激酶(p38MAPK)最早因为与应激相关而引起注意,近来发现它在多种肿瘤，包括宫颈癌,卵巢癌,肝癌,淋巴瘤中,与凋亡的启动、细胞周期的静止等密切相关,并且具有细胞特异性,在不同肿瘤细胞作用并不相同,甚至起了完全相反的作用。因此,具体研究p38MAPK信号途径在各种肿瘤及正常细胞中
