    basic FUNCTION
  • facilitating apoptosis in response to exogenous stimulation
  • playing a potential role of down-regulation in mammary carcinogenesis (Narita 2007)
  • promotes drug-induced apoptosis of cancer cells and inhibits tumorigenesis and angiogenesis (Lai 2008)
  • extracellular sulfatase acting on internal glucosamine 6-O-sulfate modifications within heparan sulfate proteoglycans and regulating their interactions with various signaling molecules, including Wnt ligands (Tang 2009)
  • extracellular sulfatases SULF1 and SULF2 remove specific 6-O-sulfate groups from heparan sulfate, thereby modulating numerous signalling pathways underlying development and homeostasis
  • SULF1 and SULF2 differentially contribute to the generation of organ-specific sulfation patterns of heparan sulfate
  • is a TGFB1)-responsive gene in normal human lung fibroblasts and functions as a negative feedback regulator of TGFB1
  • plays a crucial role in modulating both BMP and FGF signaling along the developing myoseptum to coordinate the morphogenesis of trunk musculature, associated pigment cells, and lateral line neuromasts
  • key role of SULF1 in regulating SHH-dependent neural cell diversity
  • SULF1, SULF2 plays an important role in the development of the inner ear
  • SULF1, SULF2 and EGFR are likely involved in the signalling pathway from chondroitin sulphate proteoglycans (CSPGs)that leads to inhibition of neurite outgrowth and may regulate structural plasticity and regeneration in the nervous system
  • plays a key role in cell signaling involving in cell growth, differentiation, proliferation, and migration
  • acts extracellularly to modify the structure of heparan sulfate chains to affect the bio-availability of WNT ligands
  • SULF1/SULF2 enzymes regulate cell signalling that impacts the growth and differentiation of many tissues
  • SULF1 and SULF2 play indispensable roles to maintain glomerular integrity and protective roles in diabetic nephropathy, probably by growth factor modulation
  • acts as a regulator of sonic hedgehog (SHH) signaling during embryonic ventral spinal cord development
    a component
    small molecule
  • BMP4 and BMP7 limit likely FGF10 action in the developing prostate at least in part by inducing SULF1
