CC -!- FUNCTION: Involved in the maturation of specific proteins in the
CC endoplasmic reticulum. Required for maturation and transport of active
CC lipoprotein lipase (LPL) through the secretory pathway. Each LMF1
CC molecule chaperones 50 or more molecules of LPL.
CC {ECO:0000250|UniProtKB:Q96S06, ECO:0000269|PubMed:17994020}.
CC -!- SUBUNIT: Interacts with LPL and SEL1L. {ECO:0000269|PubMed:25066055}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000269|PubMed:17994020}; Multi-pass membrane protein
CC {ECO:0000269|PubMed:17994020}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=4;
CC Name=1;

CC IsoId=Q3U3R4-2; Sequence=VSP_022974;
CC Name=3;
CC IsoId=Q3U3R4-3; Sequence=VSP_022973;
CC Name=4;
CC IsoId=Q3U3R4-4; Sequence=VSP_022975, VSP_022976;
CC -!- TISSUE SPECIFICITY: Expressed in all tissues synthesizing lipoprotein
CC lipase (Lpl) and hepatic lipase (Lipc), including adipose tissue,
CC skeletal muscle, heart, and liver. Expressed at higher levels in
CC tissues that express little or no lipase activity such as testis and
CC pancreas suggesting additional functions in these tissues.
CC {ECO:0000269|PubMed:17994020}.
CC -!- DISEASE: Note=Defects in Lmf1 are the cause of combined lipase
CC deficiency (cld). Cld is characterized by severe hypertriglyceridemia
CC with accumulation of chylomicrons that gradually pack the lumina of
CC capillaries and sinusoids. Severe hypertriglyceridemia causes an
CC increase in blood viscosity, ischemia, and cyanosis, and the inability
CC of tissues to access circulating triglycerides results in starvation,
CC poor thermoregulation, and death 2 to 3 days after birth. The disorder
CC is caused by a decrease in the activity of lipoprotein lipase (Lpl) and
CC the related hepatic lipase (Lipc), caused by impaired maturation of
CC nascent Lpl and hepatic lipase polypeptides in the endoplasmic
CC reticulum.
CC -!- SIMILARITY: Belongs to the lipase maturation factor family.
CC {ECO:0000305}.
CC -!- CAUTION: Additional evidence for its localization to the endoplasmic
CC reticulum membrane was found. However this paper was retracted due to
CC manipulation of data. {ECO:0000305|PubMed:19783858,
CC ECO:0000305|PubMed:31399538}.
