Anti-DDR1

0.5mg/ml if reconstituted with 0.2ml sterile DI water. Discoidin domain receptor family, member 1, also known as NEP, EDDR1, NTRK4, TRKE, DDR, CAK or RTK6, is a human gene. The protein encoded by this gene is a DDR that is widely expressed in normal and transformed epithelial cells and is activated by various types of collagen. This protein belongs to a subfamily of tyrosine kinase receptors with a homology region to the Dictyostelium discoideum protein discoidin I in their extracellular domain. The fibrillar collagens and immobilized collagen activated DDR1 receptor phosphorylation after prolonged treatment. Bhatt et al.(2000) showed that the protein was highly expressed in the cerebellum of developing and adult mouse brain, and that both DDR1 and Collagen IV were highly expressed in the pial layer of the cerebellar cortex. Cocultures of Collagen I- and IV-expressing mouse pial cells with DDR1-expressing granule cells resulted in granule cell neurite extension. Inhibition of collagen-DDR1 signaling reduced granule cell neurite elongation. Protein function: Tyrosine kinase that functions as cell surface receptor for fibrillar collagen and regulates cell attachment to the extracellular matrix, remodeling of the extracellular matrix, cell migration, differentiation, survival and cell proliferation. Collagen binding triggers a signaling pathway that involves SRC and leads to the activation of MAP kinases. Regulates remodeling of the extracellular matrix by up-regulation of the matrix metalloproteinases MMP2, MMP7 and MMP9, and thereby facilitates cell migration and wound healing. Required for normal blastocyst implantation during pregnancy, for normal mammary gland differentiation and normal lactation. Required for normal ear morphology and normal hearing. Promotes smooth muscle cell migration, and thereby contributes to arterial wound healing. Also plays a role in tumor cell invasion. Phosphorylates PTPN11. [The UniProt Consortium]
