Antibody Immunogen Description: Corresponds to amino acid residues A793 to V799; In protein kinase catalytic domain activation T-loop between subdomains VII and VIII.

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: DDR1 is a protein-tyrosine kinase of the TK group and DDR family an an adhesion protein. It is a cell surface receptor for fibrillar collagen and regulates cell attachment, cell migration, differentiation, and cell proliferation. It undergoes autophosphorylation in response to fibrillar collagen binding. Phosphorylation at Y396, Y703 and Y796 induces interaction with SHP2 and Y513 to Shc1. It is mainly expressed by epithelial cells in the kidneys, lungs, gastrointestinal tract, and brain, and may be activated by various types of collagen including types I, II, III, and V. DDR1 can interact with Notch1 and produce a prosurvival effect. It can also enhance cancer cell migration. DDR1 may be an oncoprotein (OP) or a tumour suppressor protein (TSP). DDR1 has been shown to be significantly overexpressed in some human tumours. It has been shown to promote the proliferation of neoplastic cells. Multiple sites of mutation lead to either inhibition or constitutively activation of this receptor. The gene expression was found to be upregulated by p53 in human osteosarcoma cells.
