Sequential Chromatography on phospho- and dephosphopeptide affinity columns.
免疫原
Phosphopeptide corresponding to amino acid residues surrounding the phospho-Ser301 of rat Raf1.
The Ras pathway is a critical signal transduction cascade involved in regulating cellular proliferation, differentiation, survival, and oncogenic transformation. Members of the Raf serine/threonine kinase family are key intermediates in this cascade, functioning to relay signals from activated Ras to the downstream protein kinases MEK and ERK (Marshall, 1996). Previous studies have shown that phosphorylation is required for Raf-1 activation (Dhillon and Kolch, 2002, Chong et al., 2003). Recent work has demonstrated that phosphorylation also regulates the downregulation of Raf (Dougherty et al., 2005) with two sites participating: Ser301 and Ser642.Synonyms: C-RAF, RAF proto-oncogene serine/threonine-protein kinase, Raf-1, cRaf
