This antibody is specific for the ~49k MEK5 protein phosphorylated at Ser311, Thr315. Immunolabeling of the MEK5 band is blocked by preadsorption with the phospho-peptide used as antigen but not be the corresponding dephospho-peptide.
Cross-Reactivity (Details)
Species reactivity (expected):Mouse, Human, Chicken, Bovine, Canine, non-Human Primates, Xenopus, and Zebrafish. Species reactivity (tested):Rat.
Purification
Sequential Chromatography on phospho- and dephosphopeptide affinity columns.
Immunogen
Phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser311, Thr315 of MEK5.
MEK5 (also known as MKK5) is a dual specificity serine/threonine protein kinase belonging to the MAP kinase kinase family. MEK5 has been shown to specifically activate ERK5 (Zhou et al., 1995) whereas MEK5 itself is regulated by MEKK3 (Chao et al., 1999). An important link between MEK5 and metastatic prostrate cancer has been demonstrated (Mehta et.al., 2003). Dual phosphorylation of Ser311 and Thr315 have been implicated in cell proliferation (Cameron et al., 2004).Synonyms: Dual specificity mitogen-activated protein kinase kinase 5, MAP kinase kinase 5, MAPKK 5, MEK5, MKK5
