Hepatic triacylglycerol lipase (LIPC, and lipoprotein lipase, LPL) are dimeric lipases (Hill et al. 1997) that hydrolyse triglycerides from circulating lipoproteins thereby playing important roles in lipoprotein remodeling and uptake. LIPC dimer (as well as LPL dimer) binds to an ER membrane protein known as lipase maturation factor 1 (LMF1) which can mediate secretion and enzymatic maturation of these lipases (Babilonia-Rosa & Neher 2014). Another family member, LMF2, may function as LMF1 based on similarity. Defects in LMF1 can cause combined lipase deficiency (CLD; MIM:246650), characterised by hypertriglyceridemia caused by ER retention of both LIPC and LPL (Peterfy et al. 2007).
