Catalog Number	P50541-M08H
Organism Species	Mouse
Host	Human Cells
Synonyms	AW495251,Ntrkr3,tyro10
Molecular Weight	The recombinant mouse DDR2 consists of 389 amino acids and has a predicted molecular mass of 44 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rm DDR2 is approximately 80-90 kDa due to glycosylation.
predicted N	Lys 22
SDS-PAGE
Purity	> 95 % as determined by SDS-PAGE
Protein Construction	A DNA sequence encoding the extracellular domain of mouse DDR2 (NP_072075.2) (Met 1-Arg 399) was expressed, with a polyhistidine tag at the C-terminus.
Bio-activity	Measured by its ability to bind rat tail Collagen I in a functional ELISA.
Research Area	Signaling |Signal Transduction |Receptor Tyrosine Kinases (RTKs)
Formulation	Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Background	Discoidin domain receptor 2 (DDR2) or CD167b (cluster of differentiation 167b) is a kind of protein tyrosine kinases associated with cell proliferation and tumor metastasis, and collagen, identified as a ligand for DDR2, up-regulates matrix metallloproteinase 1 (MMP-1) and MMP-2 expression in cellular matrix. DDR2/CD167b was found to recognise the triple-helical region of collagen X as well as the NC1 domain. Binding to the collagenous region was dependent on the triple-helical conformation. DDR2/CD167b autophosphorylation was induced by the collagen X triple-helical region but not the NC1 domain, indicating that the triple-helical region of collagen X contains a specific DDR2 binding site that is capable of receptor activation. DDR2/CD167b is induced during stellate cell activation and implicate the phosphorylated receptor as a mediator of MMP-2 release and growth stimulation in response to type I collagen. Moreover, type I collagen-dependent upregulation of DDR2/CD167b expression establishes a positive feedback loop in activated stellate cells, leading to further proliferation and enhanced invasive activity.
