背景信息

The MKK3 (Phospho-Ser189) antibody is a specialized tool used to detect the activated form of Mitogen-Activated Protein Kinase Kinase 3 (MKK3), specifically phosphorylated at serine residue 189. MKK3. also known as MAP2K3. is a serine/threonine kinase within the MAPK signaling pathway. It plays a critical role in mediating cellular responses to stress, cytokines, and growth factors by phosphorylating and activating downstream kinases like p38 MAPK. Phosphorylation at Ser189 is essential for MKK3 activation, which regulates processes such as apoptosis, differentiation, and immune responses.

This antibody is widely employed in research to study MKK3 activation dynamics in signaling pathways, particularly in models of inflammation, cancer, and neurodegenerative diseases. It is commonly used in techniques like Western blotting, immunohistochemistry, and immunofluorescence to assess MKK3 activation status in cell lines or tissues. Validation typically involves testing in knockout models or phosphorylation-blocking experiments to confirm specificity. Researchers utilize this antibody to explore how MKK3-pSer189 contributes to disease mechanisms or therapeutic responses, making it valuable for both basic and translational studies in cellular signaling.
