Antibody Code: NK241-1

Antibody Target Type: Pan-specific

Protein UniProt: P10721

Protein SigNET: P10721

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human Kit sequence peptide Cat. No.: PE-01AUS99
Antibody Immunogen Sequence: CSIHPGKSDLIVRVGD

Antibody Immunogen Description: Corresponds to amino acid residues S38 to D52; In the extracellular domain of the receptor.

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.

Scientific Background: Kit (SCFR) is a protein-tyrosine kinase of the TK group and PDGFR family. It is a receptor kinase that binds SCF/KitLG. Mast,stem cell growth factor (steel factor) binding induces Kit dimerization and autophosphorylation. Protein interactions are induced with phosphorylation at Y568 (with APS, Cbl, SHP2, & Src), Y900 (with Crk & PIK3C2A) and Y936 (with APS, Cbl, Grb2 & Grb7). Phosphorylation of S741 and S746 inhibits the kinase activity of Kit. Kit can mediate cell proliferation, survival, hematopoiesis, gametogenesis, stem cell maintenance, mast cell development, function, and migration, as well as melanogenesis. Some substrates that Kit can phosphorylate include PIK3R1, PLCG1, SH2B2/APS and CBL.This kinase is highly expressed and widely distributed in most tested human tissues. It was first identified as the cellular homologue of the feline sarcoma viral oncogene v-kit. Mutations in Kit are associated with gastrointestinal stromal tumors (GIST), mast cell leukemia, acute myelogenous leukemia (AML), and piebaldism. Kit has also been linked with the development of colorectal adenocarcinomas and melanoma progression. Insertional mutagenesis studies in mice also support a role for this protein kinase in mouse cancer oncogenesis.
