Antibody Immunogen Source: Human CSF1R (Fms) sequence peptide Cat. No.: PE-04AKC99
Antibody Immunogen Sequence: DSN(pY)IVK(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues D806 to K812. Y809 phosphorylation induces interaction with and activation of Src family members, including Fyn, Yes1 and Src as well as binding to PLCG2. Its phosphorylation stimulates receptor activation, transcription, cell cycle progression and cell growth. This phosphosite is located in the kinase activation loop between catalytic subdomains VII and VIII. This is one of the major in vivo phosphorylation sites in CSF1R (≥13 reports from high throughput mass spectrometry studies recorded in PhosphoSitePlus). CSF1R is known to be phosphorylated at this site in vitro by CSF1R.
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: CSF1R (Fms; CD115) is a member of the TK group of protein kinases in the PDGFR family. It acts as a membrane receptor for macrophage colony-stimulating factor 1 (CSF1) and IL34. It functions in the regulation of cell survival, proliferation, and differentiation in hematopoietic precursor cells as well as osteoclasts for bone metabolism. Activation of CSF1R triggers signalling pathways, including Ras/Erk and PI3K, that are crucial for myeloid cell development. Orthologues of CSF1R are highly conserved in mammals and birds. CSF1R contains a so-called kinase insert domain and is a member of the CSF1/PDGF receptor family of tyrosine-protein kinases. CSF1R is predominantly localized to the plasma membrane of myeloid lineage cells, particularly macrophages and microglia in the brain, and osteoclasts in bone. However, this kinase is highly expressed and widely distributed in most tested human tissues except in the brain and spinal cord, where it is more moderately expressed. Mutations in CSF1R have been associated with providing sustained signals for cell growth and a predisposition to myeloid malignancy. Abnormalities in CSF1R signaling are associated with hereditary diffuse leukoencephalopathy with spheroids (a neurodegenerative disease) and tumor-associated macrophages (TAMs). CSF1R has been linked with the development of acute myeloid leukemia, chronic myelomonocytic leukemia, myelodysplasia, hepatocellular carcinomas, breast cancer, and lung squamous cell carcinomas (LSCC).
