01
Overview
Mitogen-Activated Protein Kinase Kinase 5 (MEK5), also known as MAP2K5, is a dual specificity protein kinase that plays a central role in the MAP kinase signaling pathway, specifically activating ERK5. It is involved in growth factor-stimulated cell proliferation, muscle cell differentiation, and hormone-independent tumorigenesis. As a key component of the MEK5/ERK5 signaling cascade, its unique structural features make it an attractive target for therapeutic intervention, especially in oncology, where its dysregulation can drive malignancy progression or therapy resistance.
