  • N-terminal region confers a neurite-promoting activity to the protein
  • a signal peptide
  • a serpin domain
  • C terminus of PEDF (AAs 384415) represents one of the four highly conserved regions of the protein
  • secondary structure neurotrophic active site is separated from the serpin reactive-site loop, not only in the primary structure, but also in the folded protein structure

    basic FUNCTION
  • effective inhibitor of angiogenesis especially in controlling the growth of blood vessels in the eye and in bone (matrix remodeling)
  • preventing against early diabetic retinopathy
  • estrogen sensitive and inhibiting the growth of ovarian tissue
  • neuroprotective and anti-angiogenic factor, may play an important role in the pathogenesis of diabetic retinopathy
  • important neuromodulatory factor that can provide effective neuroprotection and a primary endogenous angiogenic inhibitor in the eye
  • may play a role in the pathogenesis of neurodegenerative diseases and angiogenic disorders, such as Alzheimer's disease, Parkinson disease, neovascular age-related macular degeneration and tumors
  • suspected tumor suppressor gene that plays a key role in the inhibition of epithelial tissue growth
  • inducing apoptosis in endothelial cells by activating MAPK14 dependent cleavage of multiple caspases
  • may play an important role in the pathogenesis of diabetic retinopathy, in cooperation with the VEGF gene
  • possibly involved in bone homeostasis as an inhibitor of bone resorption
  • inhibits osteoclast function via regulating osteoprotegerin expression, and thereby contributes to the maintenance of bone homeostasis
  • neurotrophic factor at first, but it also possesses neuro-protective, pro-differentiation, anti-proliferative and anti-angiogenic functions (most potent endogenous inhibitor of angiogenesis)
  • inhibits osteoclast differentiation and hence bone resorption via osteoprotegerin (OPG) and TNFSF11 (receptor activator of NF-kB ligand) in a dose-dependent manner
  • multifunctional protein and one of the strongest inhibitors of angiogenesis
  • stimulates macrophage-mediated cytotoxicity in a TNFSF10-dependent manner
  • able to enhance the antitumor efficacy of macrophages by inducing a TNFSF10-mediated tumoricidal activity
  • CELLULAR PROCESS cell life, cell death/apoptosis
    cell organization/biogenesis
  • most potent inhjbitor of angiogenesis, inhibiting advanced glycation and product-induced retinal vascular hypermeability
  • acting as a neurotrophic factor
    a component
    small molecule
  • regulated through phosphorylation by PRKACA and CSNK2A1
  • novel transcriptional target for NCOR1 repressive action
  • interaction with SERPINF1 (NCOR1 expression is required to maintain intestinal epithelial cell in a proliferative state and identify SERPINF1 as a novel transcriptional target for NCOR1 repressive action)
  • suppressed TNFSF11 activity directly and indirectly
  • TNFSF10-mediated tumoricidal activity of macrophages can be stimulated by SERPINF1
  • mediates the induction of TNFSF10 expression by PPARG
  • may regulate SOST expression by osteocytes leading to enhanced osteoblastic differentiation and increased matrix mineralization (
