MAP3K2
Introduction
Mitogen-activated protein kinase kinase kinase 2 is an enzyme that in humans is encoded by the MAP3K2 gene.[1][2][3]
Function
Function
The protein encoded by this gene is a member of serine/threonine protein kinase family. This kinase preferentially activates other kinases involved in the MAP kinase signaling pathway. This kinase has been shown to directly phosphorylate and activate IkappaB kinases, and thus plays a role in NF-kappa B signaling pathway. This kinase has also been found to bind and activate protein kinase C-related kinase 2, which suggests its involvement in a regulated signaling process.[3]
