    basic FUNCTION
  • regulator of matrix remodeling
  • activates a number of pro-MMPs
  • critical role for the generation of the fully active MMP1
  • involved in cell migration, mammary epithelial cell apoptosis and alveolar formation, mammary epithelial-mesenchymal cell conversion, generation of angiostatin-like fragment
  • involved in enhanced collagen affinity, release of bFGF, increased bioavailability of IGF1, TGF beta and cell, pro/antiinflammatory roles
  • inhibiting breast tumor cell invasion by a mechanism involving plasminogen degradation to fragments that limit plasminogen activation and the degradation of laminin
  • involved in disrupted cell aggregation and increased cell invasion
  • signaling proteinase from apoptotic neuronal cells that activates microglia, and may play a major role in degenerative brain disorders, such as Parkinson's disease
  • having a function as a trans regulator of connective tissue growth factor (CTGF)
  • plays a role in the ER stress-induced apoptosis
  • is both a direct transcriptional target and a necessa
  • involvement in digestion of SNCA in dopaminergic neurons, playing a pivotal role in the progression of Parkinson disease through modulation of SNCA in aggregation, Lewy body formation, and neurotoxicity
  • may contribute to the breakdown of articular cartilage during arthritis
  • role in the pathogenesis of idiopathic pulmonary fibrosis, through activation of beta-catenin signaling and induction of epithelial-mesenchymal transition
  • GPR65 is vital regulatory genes upstream of MMP3
  • role for SDC4 in mediating matrix degradation in both intervertebral discs and cartilage by controlling ADAMTS5 function and MMP3 expression

    Susceptibility
  • abdominal aortic aneurysm and carotid artery atherosclerosis
  • myocardial infarction
  • to Moyamoya disease (MMD)
  • Variant & Polymorphism other
  • polymorphism 5A/5A in non smocker and 6A/6A in smocker increasing the risk of acute myocardial infarction
  • the 5A allele frequency was higher in abdominal aortic aneurysm compared with controls
  • functional polymorphism in the promoter might be associated with susceptibility to MMD
