Main article: Mitogen-activated protein kinase kinase
| View/Edit Human | View/Edit Mouse |
Dual specificity mitogen-activated protein kinase kinase 2 is an enzyme that in humans is encoded by the MAP2K2 gene.[4] It is more commonly known as MEK2, but has many alternative names including CFC4, MKK2, MAPKK2 and PRKMK2. [5]
Function
The protein encoded by this gene is a dual specificity protein kinase that belongs to the MAP kinase kinase family. This kinase is known to play a critical role in mitogen growth factor signal transduction. It phosphorylates and thus activates MAPK1/ERK2 and MAPK2/ERK3.
The activation of this kinase itself is dependent on the Ser/Thr phosphorylation by MAP kinase kinase kinases.
The inhibition or degradation of this kinase is found to be involved in the pathogenesis of Yersinia and anthrax.[6]
Interactions
MAP2K2 has been shown to interact with MAPK3[7][8][9] and ARAF.[10]
