特異性：This item is specific for MEK 1 and MEK 2, (also known as MAP2K1 and MAP2K2 respectively), when phosphorylated at serine 218 and 222. MEK1 and 2 are related dual specificity protein kinases from the MAP kinase family. These proteins are activated by phosphoryation at serine 218 and 222, and play a critical role in mitogen growth factor signal transduction.
