    SUBCELLULAR LOCALIZATION     plasma membrane
  • localization of NADPH oxidase in perivascular nerve fibers
  • localized in the plasma membrane
  • basic FUNCTION
  • involved in growth control in non phagocytic cells
  • pyridine nucleotide dependent superoxide generating
  • acting as a voltage gated proton (H+) channel
  • playing a crucial role in irradiation-induced ROS generation and ROS-associated impairment of salivary gland cells
  • NOX1 mRNA and protein are overexpressed in colon cancer and are strongly correlated with activating mutations in K-Ras
  • mediates oncogenic Ras-induced upregulation of VEGF and angiogenesis by activating Sp1 through Ras-ERK-dependent phosphorylation of Sp1
  • controls the persistence of directed cell migration by a Rho-dependent switch of alpha2/alpha3 integrins
  • mediating role of NOX1-generated reactive oxygen species in cell invasion processes, most notably metalloprotease production and cell motile activity
  • involved in TP53 deacetylation and its activation may activate SIRT1 and inhibit TP53
  • controls the balance between goblet and absorptive cell types in the colon by coordinately modulating PI3K/AKT/WNT/CTNNB1 and NOTCH1 signaling
  • plays a role in host defense, cell growth and differentiation, cell migration, and malignant transformation
  • NADPH oxidase homologue which requires the regulatory subunits NOXO1 and NOXA1, as well as the flavocytochrome component CYBA for maximal activity
  • might control autocrine cell growth of liver tumor cells through regulation of the EGFR pathway
  • NOX1 and CYBB play differential roles in different platelet activation pathways and in thrombosis
  • CELLULAR PROCESS cell life, proliferation/growth
    metabolism other
    a component
  • complex consisting of NOX1, ARHGEF7, and NOXO1 is likely to be a critical step in EGF-induced reactive oxygen species generation
  • assembly of the NOX1 oxidase complex can be regulated through reversible protein-protein interactions
    small molecule
  • functionally associates with PDIA4, regulating redox-sensitive signalling pathways in a cellular context
  • RGS2 inhibits STAT3-mediated NOX1 transcription, and can itself be repressed by TLR2
