mapk通路有4种主要的分支路线: erk 、 jnk 、 p38 /mapk和erk5。 其中,JNK和p38功能相似,跟炎症、凋亡、生长都有关;ERK主要管细胞生长、分化,其上游信号是著名的 Ras/Raf 蛋白。
快速了解ERK/MAPK信号通路? - 知乎专栏
在真核细胞中已经确定了以下四条MAPK级联途径:ERK、 JNK 、 p38 MAPK 和ERK5信号转导途径。 今天我们来快速了解一下ERK/MAPK信号通路。 ERK是一种丝氨酸/苏氨酸蛋白激酶,是一种传递有丝分裂原信号的信号转导蛋白。 ERK通常位于细胞质中;在被激活后,ERK进入细胞核,调节转录因子活性和基因表达。 ERK家族已被证实包括ERK1、2、3、5和6。 其中,ERK1和ERK2是MAPK/ERK途径的两个重要成员。 ERK/MAPK信号传导途径是调节细胞生长、发育 …

Pathological roles of MAPK signaling pathways in human diseases
Persistent activation of the JNK or p38 signaling pathways has been suggested to mediate neuronal apoptosis in AD, PD, and ALS, whereas the ERK signaling pathway plays a key role in several steps of tumorigenesis including cancer cell proliferation, migration, and invasion.
ERK 通路 | Cell Signaling Technology
MAPK/Erk 信号级联放大通过生长和分化中涉及的各种不同受体进行激活,包括受体酪氨酸激酶 (RTKs)、整合素以及离子通道。 由不同的刺激物激活的级联反应的特定组分差异较大,但通路的结构通常包含一组对接蛋白(Shc、GRB2、Crk 等),它们将受体连接到一个鸟苷酸交换因子上(SOS、C3G 等),信号则转导至小分子 GTP 结合蛋白 (Ras,Rap1),后者再激活级联中的核心单位,包括一个 MAPKKK (Raf)、一个 MAPKK (MEK1/2) 和 MAPK (Erk)。 激活的 Erk 二聚 …

ERK1/2 MAP kinases: Structure, function, and regulation
2012年8月1日 · ERK1/2 are proline-directed kinases that preferentially catalyze the phosphorylation of substrates containing a Pro-Xxx-Ser/Thr-Pro sequence. Besides this primary structure requirement, many ERK1/2 substrates possess a …
Regulation of JNK and p38 MAPK in the immune system: Signal …
Significantly, pharmacological inhibition of JNK reversed the impaired activation of ERK in DUSP2-deficient cells, indicating that in the absence of DUSP2, the enhanced JNK activity mediates inhibition of ERK. Indeed, there are precedents for cross-talk amongst the MAPKs, as both p38 and JNK can negatively regulate ERK [106, 107].
