Description

DDR1 is a collagen-activated receptor tyrosine kinase that drives extracellular matrix remodeling, cell migration, and tumor invasion through SRC/MAPK signaling and upregulation of MMP2, MMP7, and MMP9—making it a compelling target in cancer biology and drug discovery. This recombinant human DDR1 construct covers the extracellular domain (aa 21–417), expressed in mammalian cells to preserve native folding and disulfide architecture critical for proper ligand and antibody recognition. Functional ELISA confirms binding activity, with immobilized DDR1 at 2 μg/mL engaging an anti-DDR1 recombinant antibody at an EC50 of 2.824–3.810 ng/mL, supporting use in receptor-ligand interaction assays, competitive blocking antibody screening, therapeutic antibody epitope mapping, and SPR- or BLI-based affinity characterization. Purity exceeding 95% by SDS-PAGE combined with endotoxin levels below 1.0 EU/μg satisfies the quality criteria typical for cell-based functional assays and small-molecule inhibitor screening campaigns.

Target Background

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.
