MEK KINASES Meaning and
Definition
-
MEK kinases, also known as mitogen-activated protein kinase kinase kinases (MAP3Ks), are a group of enzymes that play a crucial role in cellular signaling pathways. They are a subset of kinases that initiate the activation of MAP kinases, which further transmit extracellular signals into a wide range of cellular responses, including proliferation, differentiation, stress responses, and apoptosis.
MEK kinases function as upstream activators of MAP kinase kinases (MAP2Ks) or MEKs. Upon receiving signals from various extracellular stimuli, MEK kinases are phosphorylated and activated, leading to the phosphorylation and activation of MAP2Ks. Activated MAP2Ks subsequently phosphorylate and activate MAP kinases (also known as ERKs, JNKs, or p38), which in turn phosphorylate and regulate downstream target proteins involved in specific cellular processes.
The MEK kinase family is diverse, comprising multiple members, including MEKK1, MEKK2, MEKK3, MEKK4, and ASK1, among others. Each member exhibits unique regulatory roles and specificities for MAP2Ks and downstream MAP kinases, allowing for the integration of diverse extracellular signals and precise control of cellular responses.
Dysregulation of MEK kinases has been associated with numerous human diseases, including cancer, neurological disorders, and cardiovascular diseases. Accordingly, MEK kinases have become attractive therapeutic targets for drug development aiming to modulate abnormal cellular signaling and restore proper cellular functions in these diseases.

Etymology of MEK KINASES
The etymology of the term "MEK kinases" can be understood by breaking down the individual components:
1. MEK: MEK is an abbreviation for Mitogen-Activated Protein Kinase Kinase. The term "MEK" originated from its role as an upstream activator of MAPK (Mitogen-Activated Protein Kinase) in cellular signaling pathways. The acronym "MEK" was coined to describe this specific protein kinase.
2. Kinases: The word "kinase" is derived from the Greek word "kinein", which means "to move". In biology, kinases are enzymes responsible for transferring a phosphate group from ATP (adenosine triphosphate) to a substrate molecule, thereby activating or deactivating various cellular processes.
