  • basic FUNCTION
  • may be involved in cell-cell interactions and recognition
  • receptor tyrosine kinase that acts as a collagen IV adhesion receptor
  • plays an important role as a collagen receptor, mediating intimal thickening after vascular injury
  • a key mediator of the stromal-epithelial interaction during ductal morphogenesis in the mammary gland
  • central mediator of smooth muscle cell migration
  • required for cell-mediated calcification of the matrix
  • mediates an important mechanism for atherosclerotic calcification
  • regulates the stabilization of cell surface E-cadherin and E-cadherin-mediated cell aggregation
  • its expression increases epithelial plasticity
  • promotes cell-cell adhesion and differentiation through stabilization of E-cadherin, which is mediated by CDC42 inactivation
  • promotes E-cadherin-mediated adhesion
  • exerts prosurvival effect, at least in part, through the functional interaction with NOTCH1
  • acts as a novel upstream regulator for Notch1 signaling, that Notch1 functions as an important effector for DDR1-mediated survival in both the TP53-dependent and p53-independent responses to genotoxic stress
  • nonintegrin tyrosine kinase receptor for collagen implicated in cell adhesion, proliferation, and extracellular matrix remodeling
  • plays an important role in the pathogenesis of renal disease via enhanced inflammation
  • DDR1 and DDR2 are receptor tyrosine kinases that signal in response to collagen
  • while DDR1b clusters co-localized with non-fibrillar collagen, DDR1b/DDR2 filamentous structures associated with collagen fibrils

    Therapy target
    Inhibition of DDR1 expression or activity may represent a novel therapeutic target against the progression of renal diseases
    blockade of collagen-receptor DDR1 might serve as an important new therapeutic concept in progressive fibrotic and inflammatory diseases in the future
    DDR1 and DDR2 inhibition is a potential target to clear neurotoxic proteins and reduce inflammation in neurodegeneration
  • DDR1-null mice have smooth muscle cells that display reduced attachment to collagen, reduced proliferation on collagen, reduced migration toward collagen, reduced MMP2 and MMP2 expression, and targeted disruption of the DDR1 gene reduced neointimal growth after carotid injury
  • DDR1-null mice are viable but smaller in size, mutant females were unable to bear offspring, and unable unable to lactate which is caused by hyperproliferation and abnormal branching of mammary ducts
  • mice DDR1(-/-) smooth muscle cell exhibited impaired attachment to and migration toward a type I collagen substrate and MMP-2 and MMP-9 activities were concomitantly reduced
