| Enzyme Function | FUNCTION: Component of triglyceride-rich very low density lipoproteins (VLDL) and high density lipoproteins (HDL) in plasma. Plays a multifaceted role in triglyceride homeostasis. Intracellularly, promotes hepatic very low density lipoprotein 1 (VLDL1) assembly and secretion; extracellularly, attenuates hydrolysis and clearance of triglyceride-rich lipoproteins (TRLs). Impairs the lipolysis of TRLs by inhibiting lipoprotein lipase and the hepatic uptake of TRLs by remnant receptors. Formed of several curved helices connected via semiflexible hinges, so that it can wrap tightly around the curved micelle surface and easily adapt to the different diameters of its natural binding partners. {ECO:0000250|UniProtKB:P02656}. |

| Post Translational Modification | PTM: The most abundant glycoforms are characterized by an O-linked disaccharide galactose linked to N-acetylgalactosamine (Gal-GalNAc), further modified with up to 3 sialic acid residues. Less abundant glycoforms are characterized by more complex and fucosylated glycan moieties. O-glycosylated on Thr-94 with a core 1 or possibly core 8 glycan. {ECO:0000250|UniProtKB:P02656}. |
