Post Translational Modifications | Polyubiquitinated by AMFR/gp78 at Cys-280, leading to its degradation when the lipid levels are low. Association with AMFR/gp78 is mediated via interaction with INSIG1. High concentration of cholesterol and fatty acid results in Cys-280 oxidation, preventing ubiquitination at the same site, resulting in protein stabilization. Oxidized at Cys-280: high concentration of cholesterol and fatty acid induce reactive oxygen species, which oxidizes Cys-280, preventing ubiquitination at the same site, and resulting in protein stabilization. |
Function | Catalyzes the formation of fatty acid-cholesterol esters, which are less soluble in membranes than cholesterol. Plays a role in lipoprotein assembly and dietary cholesterol absorption. Utilizes oleoyl-CoA ((9Z)-octadecenoyl-CoA) and linolenoyl-CoA ((9Z,12Z,15Z)-octadecatrienoyl-CoA) as substrates. May provide cholesteryl esters for lipoprotein secretion from hepatocytes and intestinal mucosa. |
