          Product Specific Information

          This antibody is specific to MEK1.

          Target Information

          MAP2K1 (MEK1) kinase is a dual-specificity protein kinase that functions in mitogen-activated protein kinase (MAPK) cascades, controlling cell growth and differentiation. MAP2K1 is activated by a wide variety of growth factors and cytokines and also by membrane-dependent depolarization and calcium influx. Mek1 is activated by phosphorylation of serine 218 and 222 residues by Raf1. It is known to be involved in the signaling during stress activate response, apoptosis and proliferative induction by cytokines. Mutations in the gene can lead to cardiofaciocutaneous syndrome.
