Antibody Target Type: Phosphosite-specific
Antibody Phosphosite: Y531
Protein UniProt: P06241
Protein SigNET: Fyn
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Human Fyn sequence peptide Cat. No.: PE-04AKJ90
Antibody Immunogen Sequence: EPQ(pY)QPG(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues E528 to G534; in the C-terminus of the kinase. Y531 phosphorylation inhibits phosphotransferase activity of Fyn. This is the major in vivo phosphorylation sites in Fyn (≥1037 reports from high throughput mass spectrometry studies recorded in PhosphoSitePlus). Fyn is known to be phosphorylated at this site in vitro by CSK.
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: Fyn is a protein-tyrosine kinase of the TK group and Src family. It is a non-receptor kinase that mediates cell growth, survival, and adhesion. This kinase is highly expressed and widely distributed in most tested human tissues. Fyn is inhibited by phosphorylation at Y531. Fyn has been shown to phosphorylate Dab1, an intracellular adaptor protein that interacts with amyloid precursor protein (APP) and apoE receptor 2 (apoEr2). The interaction of Fyn and Dab1 regulates the phosphorylation, trafficking, and processing of APP and apoEr2. Fyn can interact with Fyn-binding protein and the p85 subunit of PI3K. It has been shown to be part of a protein complex involving DCC and FAK, which is downstream of Netrin-1, a pathway important in promoting both axonal outgrowth and axonal guidance in path finding. Fyn may be an oncoprotein (OP) based on its similarity to other Src family kinases that are known oncoproteins. Fyn expression has been shown to be significantly increased in Chronic Myelogenous Leukemia (CML). Knockdown of Fyn with shRNA slows leukemia cell growth, inhibits clonogenicity, and leads to increased sensitivity to imatinib. Fyn has also been linked with the development of lung squamous cell carcinomas (LSCC), melanomas (metastatic) and epilepsy. The active form of the protein kinase normally acts to promote tumour cell proliferation. Fyn has been linked with estrogen-receptor negative breast cancer, which is related to breast and colon cancer, and it may affect breast, lymph node, or lung tissues. Insertional mutagenesis studies in mice also support a role for this protein kinase in mouse cancer oncogenesis. This description may include information annotated by UniProt and/or Google AI.
