    SUBCELLULAR LOCALIZATION     intracellular
  • cytoplasmic in the liver and also associated with mitochondria especially in steroidogenic tissues
  • isoform SCPx resides in the peroxisome
  • basic FUNCTION
  • SCPx isoform is a peroxisomal thiolase cleaving 2-methyl branched chains mediating intracellular cholesterol in steroidogenic tissues
  • facilitates cholesterol (Ch) and phospholipid (PL) transfer/exchange between membranes and appears to play a key role in intracellular lipid trafficking
  • playing a role in intracellular phosphatidylinositol transfer, distribution, and signaling
  • enhances cholesterol retention within the cell as well as regulates the distribution of signaling lipids, such as phosphoinositides and sphingolipids, at plasma membrane caveolae
  • FABP1 and SCP2 facilitate the preferential movement of HDL-associated cholesteryl esters (HDL-CEs) to bile for final elimination
