    mitogen-activated protein kinase kinase kinase 5

  • Overview

    Mitogen-activated protein kinase (MAPK) signaling cascades include MAPK or extracellular signal-regulated kinase (ERK), MAPK kinase (MKK or MEK), and MAPK kinase kinase (MAPKKK or MEKK). MAPKK kinase/MEKK phosphorylates and activates its downstream protein kinase, MAPK kinase/MEK, which in turn activates MAPK. The kinases of these signaling cascades are highly conserved, and homologs exist in yeast, Drosophila, and mammalian cells. MAPKKK5 contains 1,374 amino acids with all 11 kinase subdomains. Northern blot analysis shows that MAPKKK5 transcript is abundantly expressed in human heart and pancreas. The MAPKKK5 protein phosphorylates and activates MKK4 (aliases SERK1, MAPKK4) in vitro, and activates c-Jun N-terminal kinase (JNK)/stress-activated protein kinase (SAPK) during transient expression in COS and 293 cells; MAPKKK5 does not activate MAPK/ERK.

What is MAP3K5 protein?

Mitogen-Activated Protein Kinase Kinase Kinase 5, or MAP3K5 protein for short, this particular protein carries an array of responsibilities in several critical cellular processes. The discovery of MAP3K5 dates back to studies undertaken in the early 1990s where it was found to be among the family of serine/threonine-protein kinases and is encoded by the MAP3K5 gene. Conserved across several species, MAP3K5 is scientifically recognized as MKK Kinase, sometimes referred to as Apoptosis Signal-regulating Kinase 1 (ASK1) due to its essential role in cellular death processes.

The MAP3K5 gene in humans is found on the chromosome 6, precisely at the locus 6q22.33 which highlights the physical and genetic position of where the protein does originate from an individual's genetic makeup.

Protein Structure

The MAP3K5 protein structure comprises several functional domains. It includes a C-terminal region with an important kinase domain that contains a catalytic core structure typical of serine/threonine-protein kinases. Notably, it also includes a serine-rich region associated with regulatory phosphorylation sites, N-terminal domain holds a protein-protein interaction domain coiled-coil, and a nuclear export signal (NES) and nuclear localization signal (NLS) sequences.

What are the functions of MAP3K5 protein?

Functionally, MAP3K5 protein engages in various processes driving essential functions of life in living organisms. This protein acts as a nodal point in the MAPK signaling pathway, receiving signals from various receptors and delivering them to downstream effectors. It activates two main subfamilies of MAP2Ks: MKK4/MKK7 (which activate JNK pathway) and MKK3/MKK6 (which activate the p38 pathways).

MAP3K5 protein plays a crucial role in numerous physiological processes ranging from apoptosis, inflammation, response to oxidative stress, cell differentiation to immune response. This protein is pivotal in mediating apoptosis (programmed cell death), a vital process in human health and disease. During oxidative stress, MAP3K5 is activated, leading to apoptosis for the preservation of organismic integrity.

MAP3K5 Protein Related Signal Pathway

The MAP3K5 protein plays a critical role in the MAPK signaling pathway. The Mitogen-activated protein kinase (MAPK) pathway is a biochemical route in the cell that transmits information from the cell surface to the DNA in the nucleus, ultimately influencing genetic activity. The MAPK pathways are vital for various cellular functions including survival, proliferation, differentiation, and apoptosis.

MAP3K5 protein, as a component of the MAPK signaling pathway, functions at the upstream level where it receives and processes signals before transmitting them to downstream components. The protein is involved in the activation of both the p38 MAPK and the JNK MAP kinase pathways.

MAP3K5 Protein Related Diseases

utation or deviation from normal functionality of MAP3K5 protein has links with several diseases. Given its central role in a variety of physiological processes, abnormalities in the MAP3K5 protein can lead to complexities. Evidence suggests it in the pathophysiology of neurodegenerative diseases like Alzheimer's and Parkinson's disease. In Alzheimer's disease, for example, the role of MAP3K5 protein in neuronal death presents the possibility of it being a potential therapeutic target.

Additionally, aberrations in the MAP3K5 protein and its pathways have been implicated in cancer biology. Studies have shown that MAP3K5 protein might endorse tumor growth in certain types of cancer, such as lung and breast cancer. Notably, more studies are needed in this area to fully elucidate causal or correlational relationships.

MAP3K5 Protein's Applications

Applications of MAP3K5 protein lie predominantly within the research and medicinal fields. As it plays a pivotal role in diseases like Parkinson's, Alzheimer's, and certain cancers, it is the subject of rigorous studies aiming to establish new treatment modalities. The protein's role in critical pathways and processes has drawn scientific interest, making it a target for drug discovery and development.

Targeting the MAP3K5 protein could potentially mitigate the progression of neurodegenerative diseases and slow cancer growth. Nevertheless, while the promise is evident, further research is required to ensure these treatments' safety and efficacy, considering the MAP3K5 protein's broad impact across various cellular functions.
