Antibody Target Type: Pan-specific

Protein UniProt: P36888

Protein SigNET: P36888

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human Flt3 (STK1) sequence peptide Cat. No.: PE-01AUK85

Antibody Immunogen Sequence: CKHPSQSALVTIVEKG

Antibody Immunogen Description: Corresponds to amino acid residues K334 to G348

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.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Antibody Concentration: 0.5 mg/ml

Antibody Cross Reactivity: No immunoreactivity on protein dot blots with recombinant human CSF1R and Kit.
Scientific Background: Flt3 (FLK2) is a protein-tyrosine kinase of the TK group and PDGFR family. It is involved in cell proliferation, differentiation and survival through the binding of its ligand, Flt3LG. Autophosphorylation of Y591 increases phosphotransferase activity. Autophosphorylation of Y599 increases phosphotransferase activity and induces interaction with SHP2 and Src. Flt3 will induce phosphorylation of Shc1 and Akt1 leading to a change in the downstream regulator mTOR. It can activate the Ras signalling pathway and lead to phosphorylation of downstream kinases such as MAPK1/ERK2 and MAPK3/ERK1. Mutations causing constitutive activity promote cell proliferation and resistance to apoptosis. Defects have been associated with acute myelogenous leukemiaFlt3 is a known oncoprotein (OP). Cancer-related mutations in human tumours point to a gain of function of the protein kinase. The active form of the protein kinase normally acts to promote tumour cell proliferation. Flt3 is linked with Acute Myeloid Leukemia (AML), Juvenile Myelomonocytic Leukemia (JMML), Myelodysplastic Syndromes (MSD), Acute Promyelocytic Leukemia, Myeloid Sarcoma, Chronic Myeloproliferative Disease (CMPD), Acute Biphenotypic Leukemia (BAL), Precursor T-Cell Acute Lymphoblastic Leukemia, Leukemia, Acute Lymphoblastic 3 (B-ALL), Acute Myeloblastic Leukemia with Maturation, Minimally Differentiated Acute Myeloblastic Leukemia is a subtype of AML, and Gastrointestinal Stromal tumour (GANT). STAT5A activation involves Y589 and Y591 phosphorylation. A Y599F mutation can interrupt Flt3 complex formation with PTPN11/SHP2.
