Key result
The ANGPTL3/8 complex promotes furin-mediated LPL cleavage and inhibits LPL enzymatic activities more strongly than ANGPTL3 or ANGPTL8 alone.
Why the study?
The ANGPTL3/8 complex is a potent endogenous inhibitor of LPL, but the nature of the structural interaction between ANGPTL3/8 and LPL was unknown.
The study reveals that the ANGPTL3/8 complex inhibits lipoprotein lipase by promoting its furin-mediated cleavage, offering mechanistic insights into lipid metabolism.

Does not yet alter clinical lipid management; extends preclinical insights into ANGPTL3/8-LPL regulation.
Jin et al. (2021) studied this question. ANGPTL3/8 complex vs. ANGPTL3 or ANGPTL8 alone was evaluated on LPL enzymatic activities and LPL cleavage. The ANGPTL3/8 complex promotes furin-mediated LPL cleavage and inhibits LPL enzymatic activities more strongly than ANGPTL3 or ANGPTL8 alone.
