补充信息

MEK4 also known as MKK4 is a protein kinase with a molecular weight of approximately 43 kDa. It functions as a dual-specificity kinase that phosphorylates and activates other kinases in cellular signaling pathways. MEK4 appears in various tissues including heart brain and skeletal muscle. It acts as an essential component in transmitting extracellular signals to downstream effectors and is involved in critical cellular processes like proliferation differentiation and apoptosis.

Biological function summary

MEK4 acts as an upstream kinase in the MAPK signaling cascade. Through its role in this pathway it is part of a larger signaling complex. MEK4 specifically activates JUN N-terminal kinase (JNK) by phosphorylation. JNK further regulates gene expression by influencing transcription factors impacting cellular responses. This makes MEK4 a pivotal element in facilitating messenger roles that allow cells to adapt to changing environments such as stress responses and immune reactions.

Pathways

MEK4 plays significant roles in the MAPK and stress-activated protein kinase (SAPK) pathways. In the MAPK pathway MEK4 phosphorylates JNK thereby influencing cellular responses to environmental changes. Within the SAPK pathway MEK4 interacts with other kinases such as MKK7 to modulate cellular responses further. The flow of signals through these pathways affects cell fate cell cycle regulation and programmed cell death demonstrating its comprehensive influence on cell physiology.

MEK4 shows involvement in cancer progression and neurodegenerative diseases. Abnormal activation of MEK4 can contribute to tumor growth and metastasis in cancers such as prostate and ovarian cancer by enhancing JNK signaling. In neurodegenerative disorders deregulation of MEK4-related pathways might lead to neuronal damage or apoptosis. Proteins like JNK and other MAP kinases become dysregulated in these conditions illustrating the interconnected role of MEK4 in disease mechanisms. Phospho flow cytometry can be utilized to measure alterations in MEK4 phosphorylation states aiding in elucidating its role in disease contexts.

靶点信息

Dual specificity protein kinase which acts as an essential component of the MAP kinase signal transduction pathway. Essential component of the stress-activated protein kinase/c-Jun N-terminal kinase (SAP/JNK) signaling pathway. With MAP2K7/MKK7, is the one of the only known kinase to directly activate the stress-activated protein kinase/c-Jun N-terminal kinases MAPK8/JNK1, MAPK9/JNK2 and MAPK10/JNK3. MAP2K4/MKK4 and MAP2K7/MKK7 both activate the JNKs by phosphorylation, but they differ in their preference for the phosphorylation site in the Thr-Pro-Tyr motif. MAP2K4 shows preference for phosphorylation of the Tyr residue and MAP2K7/MKK7 for the Thr residue. The phosphorylation of the Thr residue by MAP2K7/MKK7 seems to be the prerequisite for JNK activation at least in response to pro-inflammatory cytokines, while other stimuli activate both MAP2K4/MKK4 and MAP2K7/MKK7 which synergistically phosphorylate JNKs. MAP2K4 is required for maintaining peripheral lymphoid homeostasis. The MKK/JNK signaling pathway is also involved in mitochondrial death signaling pathway, including the release cytochrome c, leading to apoptosis. Whereas MAP2K7/MKK7 exclusively activates JNKs, MAP2K4/MKK4 additionally activates the p38 MAPKs MAPK11, MAPK12, MAPK13 and MAPK14.
