Antibody Code: PK594

Antibody Target Type: Phosphosite-specific

Antibody Phosphosite: Y740

Protein UniProt: Q16832

Protein SigNET: Q16832

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human DDR2 (Tyro10) sequence peptide Cat. No.: PE-04AHA99

Antibody Immunogen Sequence: SGD(pY)YRI(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues S737 to I743; 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: DDR2 is a protein-tyrosine kinase of the TK group and DDR family. It is a receptor kinase that binds fibrillar collagen and has roles in the regulation of cell differentiation, extracellular matrix remodeling, cell migration, and cell proliferation. DDR2 is necessary for normal bone development and promotes fibroblast migration and proliferation, and has a critical role in wound healing. This kinase is highly expressed and widely distributed in most tested human tissues except in the brain where it is poorly expressed. Orthologues of DDR2 are highly conserved in vertebrates and insects. Phosphorylation of DDR2 at Y471 induces interaction with Shc1, whereas phosphorylation at Y740 induces interaction with Nck2 and SHP2. DDR2 isfeatures a distinct extracellular region encompassing a factor VIII-like domain, which is thought to be involved in the regulation of cell growth, differentiation, and metabolism. DDR2 plays a role in the regulation of collagen turnover mediated by smooth muscle cells in obstructive diseases of blood vessels and the lung. DDR2 has also been linked with the development of lung large cell carcinomas and spondyloepimetaphyseal dysplasia short limb-hand type (semd-sl).
