Antibody Target Type: Phosphosite-specific
Antibody Phosphosite: Y302
Protein UniProt: P10398
Protein SigNET: RafA
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Human Raf-A (ARaf) sequence peptide Cat. No.: PE-04AFW99
Antibody Immunogen Sequence: SGY(pY)WEV(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues S299 to V305; Just before kinase catalytic domain. Y302 phosphorylation stimulates phosphotransferase activity. This is one of the major sites of in vivo phosphorylation of Raf-A based on ≥97 mass spectrometry reports recorded in PhosphoSitePlus. Raf-A is known to be phosphorylated at this site in vitro by Src.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.This antibody was also subject to negative purification over phosphotyrosine-agarose.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: A-Raf (RafA) is a protein-serine/threonine kinase of the TKL group and Raf family. It is involved in the transduction of mitogenic signals from the cell membrane receptors via Ras and MEK1/2 to the nucleus. It has been implicated in playing a role in the postsynaptic responses of hippocampal neuron. Phosphorylation of Ser-214, Ser-257, Ser-262, Ser-264, Tyr-301, Tyr-302, Ser-432, Thr-442, Thr-452, Thr-455 and Ser-582 all contribute to increased phosphotransferase activity. It is inhibited by Nexavar/Sorafenib (IC50>50 nM). A-Raf may be an oncoprotein (OP) based on its similarity to Raf1 and B-Raf. However, it does not display a higher than normal rate of mutation than most proteins in human tumours. The active form of the protein kinase acts to promote tumour cell proliferation.
