MAPK8
-
Official Full Name
mitogen-activated protein kinase 8 -
Overview
The c-Jun N-terminal protein kinases (JNKs) are a family of serine/threonine protein kinases of the mitogen-activated protein kinase (MAPK) group. JNKs, which are essential regulators of physiological and pathological processes, are involved in several diseases including diabetes, atherosclerosis, stroke, and Parkinson"s and Alzheimer"s diseases. The JNK family consists of three isoforms; JNK1 and JNK2, which are ubiquitous, and JNK3, which is present primarily in the heart, brain and testis. Differential splicing and exon use yield 10 isoforms of JNK. JNK1 is an important mediator of insulin resistance associated with obesity, but it is also indispensable for the intact cytoarchitecture of the brain. -

Background
What is mapk8 protein?
MAPK8 protein, also known as c-Jun N-terminal kinase 1 (JNK1), is a member of the mitogen-activated protein kinase (MAPK) family. It plays a crucial role in various cellular processes, including cell proliferation, differentiation, apoptosis, and immune response.
MAPK8 protein has been implicated in several biological processes and diseases. It has been associated with inflammation, cancer development and progression, neuronal cell survival, and response to stress and environmental stimuli. Dysregulation of MAPK8 signaling has also been linked to neurodegenerative diseases, inflammatory bowel disease, and cardiovascular disorders.
What is the function of mapk8 protein?
In biomedical research, understanding the function and regulation of MAPK8 protein is crucial for developing therapeutic interventions for various diseases. The development of specific inhibitors or activators that target the MAPK8 pathway holds promise for treating conditions such as cancer, inflammation, and neurodegenerative disorders.
Mapk8 related signaling pathway
The MAPK8 protein is involved in a signaling pathway known as the JNK signaling pathway. Upon activation, MAPK8 phosphorylates downstream target proteins, including transcription factors such as c-Jun, ATF2, and Elk-1, leading to gene expression changes and modulation of cellular responses.
Mapk8 Related Diseases
- Cancer: MAPK8 plays a role in tumor development and progression. Abnormal activation of MAPK8 signaling has been found in various cancers, including breast, lung, colon, and pancreatic cancer. Inhibition of MAPK8 signaling is being explored as a potential therapeutic target for cancer treatment.
- Neurodegenerative diseases: Activation of MAPK8 has been observed in neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and Huntington's disease. The dysregulation of MAPK8 signaling contributes to neuronal cell death and neuroinflammation in these diseases.
- Cancer therapy: MAPK8 plays a role in regulating cell proliferation, survival, and apoptosis, making it a potential target for cancer therapy. Inhibition of MAPK8 activity has been explored as a strategy to suppress tumor growth and induce apoptosis in cancer cells.
Biomedical Application of mapk8 Protein
- Cancer therapy: MAPK8 plays a role in regulating cell proliferation, survival, and apoptosis, making it a potential target for cancer therapy. Inhibition of MAPK8 activity has been explored as a strategy to suppress tumor growth and induce apoptosis in cancer cells.
- Neuroprotection: MAPK8 is involved in neuronal cell survival and death pathways. Activation of MAPK8 has been shown to protect neurons from various insults, such as oxidative stress and excitotoxicity. Therefore, modulation of MAPK8 activity holds therapeutic potential for neurodegenerative diseases.

Fig3. PGF-activated MAPK8 and MAPK14 signaling pathways are involved in PGF-induced autophagy. (A and B) BEAS-2B cells were pretreated with 100 ng/ml recombinant human PGF for 0 to 24 h. PGF-induced phosphorylation of MAPK8 and MAPK14 was assessed by western blot analysis for p-MAPK8 and p-MAPK14 (A) and the quantitative results are shown in (B).
