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 D-docking site, an F-docking site, or both.

In molecular biology, extracellular signal-regulated kinases (ERKs) or classical MAP kinases are widely expressed protein kinase intracellular signalling molecules that are involved in functions including the regulation of meiosis, mitosis, and postmitotic functions in differentiated cells.

ERK进入细胞核后直接磷酸化转录因子Elk-1的多个位点，如Ser383 和 Ser389 等。 磷酸化后的Elk-1构象发生改变，与血清反应因子（SRF）的相互作用，形成高活性的转录因子复合物。

ERK是extracellular regulated protein kinases的英文缩写，指细胞外调节蛋白激酶，包括ERK1和ERK2，是将信号从表面受体传导至细胞核的关键。许多其他信号通路明显活化时，可活化蛋白激酶ERK信号通路，ERK明显活化时，也可活化其他信号通路。

Extracellular signal-regulated protein kinases 1 and 2 (ERK1/2) are members of the mitogen-activated protein kinase super family that can mediate cell proliferation and apoptosis. The Ras–Raf–MEK–ERK signaling cascade controlling cell proliferation has been well studied but the mechanisms involved in ERK1/2-mediated cell death are largely unknown.

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。

Jun 23, 2020 · We begin with a brief overview of the structure, regulation, substrate recognition and subcellular localization of ERK1 and ERK2. We then systematically discuss how ERK signalling regulates six...

In this review we compiled data on ERK1 vs. ERK2 gene structures, protein sequences, expression levels, structural and molecular mechanisms of activation and substrate recognition.

Aug 1, 2012 · 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 D-docking site, an F-docking site, or both.

The extracellular signal-regulated kinases 1 and 2 (ERK) cascade, member of the mitogen-activated protein kinases superfamily of signalling pathways, is one of the best characterized pathways as many protein interactions and phosphorylation events ...
