  • expressed in chromaffin cells, sorted into the regulated pathway of secretion (into catecholamine storage vesicles)
    • basic FUNCTION
  • inhibiting extracellular matrix degradation by PLAU
  • putative upregulated c-Myc target gene
  • playing a key role in control of coagulation and tissue remodeling
  • is an intracellular inhibitor of furin, having an active role in the development of metabolic disorders
  • antiapoptotic role for SERPINE1 that may contribute to its participation in neutrophil-associated inflammatory responses (
  • endothelial plasminogen activator inhibitor SERPINE1, controls vascular remodeling, angiogenesis and fibrinolysis
  • playing a role in regulation of angiogenesis
  • involved in the innate immunity by regulating cell migration and phagocytosis
  • glia-derived SERPINE1 may regulate microglial migration and phagocytosis in an autocrine or paracrine manner
  • promotes the proliferation, transforming into myofibroblasts, collagen synthesis, and inhibits apoptosis of pulmonary fibroblasts by activating Ca(2+), ERK and AKT signaling pathway

    protein
  • binding of ELK1 to the SERPINE1 promoter and ELK1 phosphorylation on the Ets binding site is EGF-dependent
  • while SERPINE1 and SERPINB2 function similarly in the control of cellular plasmin generation by PLAT, they may have disparate effects on the alternative functions of PLAT via modulation of its engagement with endocytosis receptors
  • plays a critical role in mediating fibrosis caused by AGT and lends weight-of-evidence to a pro-fibrotic role of this protein in liver
  • DLC1 modulates the expression of SERPINE1, which is a negative regulator for cell migration, in a GAP domain and EGFR-MEK-dependent manner
  • the contribution of EGF to the regulation of SERPINE1 involves the MAPK pathway, and the synergistic interface with the TGFB pathway is downstream of MEK1/2 and involves phosphorylation of neither ERK1/2 nor SMAD2/3
  • estrogen regulates endothelial migration via SERPINE1
  • critical downstream target of SERPINE1-induced senescence
  • PLAT-SERPINE1 system regulates the senescence-inducing activity of IGFBP3
  • proapoptotic function of SERPINE1 is mediated through vitronectin (VTN) inhibition
