The function of ENSG00000011638 (LDAF1, lipid droplet assembly factor 1) is as follows. Plays an important role in the formation of lipid droplets during the differentiation and maturation of adipocytes (PubMed:31708432). Together with seipin (BSCL2), defines the sites of lipid droplet formation in the endoplasmic reticulum and promotes the aggregation of triacylglycerol molecules to form the core of a lipid droplet (nucleation) in the endoplasmic reticulum and drive budding of lipid droplets into the cytoplasm (PubMed:31708432). .
