CATEGORY

regulatory

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm,organelle,membrane
	intracellular,cytoplasm,organelle,endoplasmic reticulum
text	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
