  • hydrophobic ligand binding proteins
  • CATEGORY transport carrier
    SUBCELLULAR LOCALIZATION     intracellular
  • cytoplasmic in absence of alpha-tocopherol
  • nuclear in presence of alpha-tocopherol
  • basic FUNCTION
  • playing a role in an intracellular transport system
  • having a transcriptional activatory activity via its association with alpha-tocopherol
  • may modulate, in a tocopherol-sensitive manner, phosphatidylinositol-3-kinase, a central enzyme in signal transduction, cell proliferation, and apoptosis
  • regulating cholesterol biosynthesis by increasing the transfer of squalene to a metabolic active pool in the cell
  • stimulates squalene monooxygenase, a downstream enzyme in the cholesterol biosynthetic pathway)
  • may act as an intracellular shuttle for alpha-TOS (Alpha-tocopheryl succinate), promoting apoptosis initiated by this vitamin E analogue
  • may participate in intracellular lipid transport (phospholipids, squalene, tocopherol analogues and derivatives) or influence regulatory lipid-dependent events
  • may mediate lipid uptake, secretion, presentation, and sub-cellular localization in a tissue-specific manner, possibly using organelle- and enzyme-specific docking sites
  • may serve as a tumor suppressor in breast carcinogenesis
  • may participate in intracellular lipid transport and influence regulatory lipid-dependent events
