  • transmembrane protein that resides in the endoplasmic reticulum and concentrates at junctions between the ER and cytosolic lipid droplets
  • basic FUNCTION
  • may play a role in the differentiation of mesenchymal cells into preadipocyte
  • involved in droplet assembly and/or maintenance
  • strongly induced during adipocyte differentiation, and the induction of BSCL2 expression was essential for adipogenesis
  • essential, cell-autonomous regulator of adipogenesis
  • required for normal lipid droplet morphology
  • playspotentially at least a structural role in organizing droplets or in communication between droplets and ER
