Component of a protein kinase signal transduction cascade. Regulates the JNK and ERK5 pathways by phosphorylating and activating MAP2K5 and MAP2K7 (By similarity). Plays a role in caveolae kiss-and-run dynamics
Tissue Specificity
A synthetic peptide corresponding to residues near the N-term of human MEKK-2 was used as immunogen.
Cellular Localization
Cytoplasm. Nucleus. Note=Upon EGF stimulation, translocates into the nucleus
