MEK kinase-3 Antibody (40) is a mouse monoclonal IgG1 kappa light chain antibody that detects MEK kinase-3 protein of mouse, rat, human, and canine origin by western blotting (WB), immunoprecipitation (IP), and immunofluorescence (IF). Anti-MEK kinase-3 antibody (40) is available as non-conjugated format. MEK kinase-3 plays a crucial role in mitogen-activated protein (MAP) kinase signaling pathways, which are essential for cellular responses to various extracellular stimuli, including growth factors. Specifically, MEK kinase-3 is involved in phosphorylation and activation of downstream MAP kinases, such as ERK, JNK, and p38, which are pivotal for regulating processes like cell proliferation, differentiation, and survival. Precise regulation of these pathways is vital for maintaining normal cellular functions and preventing diseases such as cancer, where aberrant signaling can lead to uncontrolled cell growth. Additionally, MEK kinase-3 is preferentially activated by MEK kinase-3 itself, highlighting its importance in the signaling cascade. Understanding the interactions and regulatory mechanisms of MEK kinase-3 can provide insights into therapeutic targets for various diseases, making anti-MEK kinase-3 antibody (40) an invaluable tool for researchers studying these critical pathways.
