MEKK3 also known as MAP3K3 is a serine/threonine kinase that plays an important role in the MAPK signaling cascade. This protein has a molecular mass of approximately 67 kDa. MEKK3 is widely expressed with notable presence in tissues like the heart placenta and skeletal muscles. It is important for transmitting signals from the cell surface to various intracellular targets impacting numerous cellular processes.

Biological function summary

MEKK3 participates in cell growth differentiation and apoptosis regulation. It often functions within a multi-protein complex including components like MEK5 and ERK5. MEKK3 activates downstream kinases influencing gene expression and cellular responses to external signals. Its involvement is essential for controlling reactions to stress and inflammatory stimuli.

Pathways

MEKK3 integrates into the MAPK and NF-κB pathways both critical for mediating signaling responses. In the MAPK pathway MEKK3 regulates kinases like MEK5 and ERK5. Additionally it connects with proteins such as IKK in the NF-κB pathway influencing immunity and cell survival. These interactions position MEKK3 centrally in cellular defense and adaptability mechanisms.

MEKK3 associates with pathological conditions like cardiovascular diseases and cancer. Its role in these disorders links closely with dysregulation in the MAPK pathway where MEK5 and ERK5 also play significant roles. Furthermore aberrations in the NF-κB pathway involving IKK can contribute to its involvement in these diseases highlighting MEKK3's impact on disease progression and potential as a therapeutic target.
