Activity summary

ERK5 also known as big MAP kinase 1 (BMK1) is an enzyme that functions as a protein-serine/threonine kinase within the MAP kinase family. It has a molecular weight of approximately 120 kDa. ERK5 is expressed in various tissues including the brain heart and lungs with notable expression in endothelial cells. The protein plays a mechanical role in signal transduction processes which it achieves by transmitting signals from extracellular sources to the cellular nucleus facilitating the regulation of gene expression.

Biological function summary

ERK5 influences cellular functions through its role in promoting cell proliferation and differentiation. It serves as part of a signaling complex that includes the MAP kinase kinase 5 (MEK5). This interaction allows ERK5 to phosphorylate and subsequently activate target substrates such as transcription factors promoting cellular responses necessary for development and survival. ERK5 also plays a role in the response to oxidative stress which contributes to its impact on survival pathways and cellular stress responses.

Pathways

ERK5 acts within the MAPK signaling cascade and is linked to the ERK/MAPK pathway and the phosphoinositide 3-kinase (PI3K) pathway. Within these pathways ERK5 interacts with other MAP kinases and regulatory proteins such as Ras and Raf contributing to a wide range of cellular processes including growth migration and survival. Through these interactions ERK5 influences cellular dynamics and mediates responses to growth factors and stress stimuli.

Associated diseases and disorders

Abnormal activity of ERK5 has been implicated in various conditions including cardiovascular disease and cancer. Elevated ERK5 signaling can promote tumor progression and metastasis in certain cancers by enhancing tumor cell proliferation and survival. In cardiovascular disorders ERK5 interacts with proteins like calcium/calmodulin-dependent protein kinase II (CaMKII) influencing pathological cardiac remodeling and hypertrophy. These associations highlight ERK5's impact on disease mechanisms and highlight its potential as a therapeutic target.
