Full Product Name

DDR2, Recombinant, Human (Discoidin Domain Receptor 2)

Research Use Only
For Research Use Only. Not for use in diagnostic procedures.
Chromosome Location
Chromosome: 1; NC_000001.10 (162602228..162756409). Location: 1q23.3
3D Structure
ModBase 3D Structure for Q16832
Highly Purified
95%, as determined by SDS-PAGE and visualized by silver stain.
Supplied as a lyophilized powder from a 0.2um filtered solution in PBS.
Measured by its ability to bind collagen I (1ug/ml, 100 L/well) in a functional ELISA with an apparent Kd < 10 nM.
Endotoxin Level
< 1.0 EU per 1 g of the protein as determined by the LAL method.
It is recommended that sterile PBS be added to the vial to prepare a working stock solution of no less than 100ug/ml. The carrier-free protein should be used immediately upon reconstitution to avoid losses in activity due to non-specific binding to the inside surface of the vial. For long term storage as a dilute solution, a carrier protein (e.g. 0.1% HSA or BSA) should be added to the vial.
Preparation and Storage
Lyophilized samples are stable for up to twelve months at -20 degree C. Upon reconstitution, this protein, in the presence of a carrier protein, can be stored under sterile conditions at 2-8 degree C for one month or at -20 degree C in a manual defrost freezer for three months without detectable loss of activity. Avoid repeated freeze-thaw cycles.
Other Notes
Small volumes of DDR2 recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

DDR2 recombinant protein
DDR-2, also known as TYR010 and TKT, is a widely expressed 130kD type I transmembrane glycoprotein belonging to the discoidin-like domain containing subfamily of receptor tyrosine kinases (1). Mature human DDR-2 consists of a 378 aa extracellular domain (ECD) that includes the discoidin-like domain, a 22 aa transmembrane segment, and a 434 aa cytoplasmic domain that includes the kinase domain (2). Within the ECD, human DDR-2 shares 53% aa sequence identity with DDR-1 and 97% aa sequence identity with mouse DDR-2. The discoidin-like domain mediates DDR-2 interactions with collagens I, III, and X (3-5). Collagens II and V are less efficacious ligands (3). DDR-2 selectively recognizes the triple helical structure of collagen compared to monomeric or denatured collagen (3, 5, 6). Within collagen II, the D2 period is required for DDR-2 binding, and the D1 period is additionally required to trigger DDR-2 autophosphorylation (6). The ECD of DDR-2 exists as a non-covalent dimer in solution, and dimerization of the receptor greatly enhances collagen binding (4, 7). DDR-2 interaction with collagen I inhibits collagen fibrillogenesis and alters collagen fiber morphology (7). Ligand binding induces DDR-2 autophosphorylation in the cytoplasmic domain (3, 5, 8), which promotes associations with Shc and Src (9). In addition to the above mechanism, DDR-2 exhibits a distinct interaction with collagen X. A region other than the discoidin-like domain of DDR-2 recognizes the non-helical NC1 domain of collagen X, and this interaction does not lead to receptor autophosphorylation (5). Activation of DDR-2 by collagen induces upregulation of MMP-1, -2, and -13 as well as DDR-2 itself (3, 8, 10). DDR-2 is implicated in collagenous matrix destruction and cell invasiveness (8, 10). DDR-2 is also upregulated in several pathological conditions, including hepatic fibrosis following injury, rheumatoid and osteoarthritis, and smooth muscle cell hyperplasia (8, 10-12).

NCBI Summary for DDR2
Receptor tyrosine kinases (RTKs) play a key role in the communication of cells with their microenvironment. These molecules are involved in the regulation of cell growth, differentiation, and metabolism. In several cases the biochemical mechanism by which RTKs transduce signals across the membrane has been shown to be ligand induced receptor oligomerization and subsequent intracellular phosphorylation. This autophosphorylation leads to phosphorylation of cytosolic targets as well as association with other molecules, which are involved in pleiotropic effects of signal transduction. RTKs have a tripartite structure with extracellular, transmembrane, and cytoplasmic regions. This gene encodes a member of a novel subclass of RTKs and contains a distinct extracellular region encompassing a factor VIII-like domain. Alternative splicing in the 5' UTR results in multiple transcript variants encoding the same protein. [provided by RefSeq, Jul 2008]
