Supplementary information

ACAT1 also known as acyl-CoA:cholesterol acyltransferase 1 is an enzyme that catalyzes the formation of cholesteryl esters from cholesterol and long-chain fatty acyl-CoA. It has a molecular mass of approximately 50 kDa. ACAT1 is present in the endoplasmic reticulum membrane and is expressed widely including in liver adrenal glands and macrophages. The enzyme's activity is significant in lipid metabolism storing cholesterol as cholesteryl esters.
Biological function summary

ACAT1 plays a central role in cellular cholesterol homeostasis and in preventing cholesterol-induced cytotoxicity by converting free cholesterol into inert cholesteryl esters for storage. It functions as a homotetramer suggesting that it works as a part of a larger protein complex. ACAT1 influences lipid accumulation within cells and mediates the regulation of cholesterol levels which is vital for maintaining membrane integrity and cellular function.

Pathways

ACAT1 participates in the cholesterol metabolism pathway and the lipid biosynthesis pathway. It interacts with proteins such as LDLR (low-density lipoprotein receptor) by controlling the availability of free cholesterol within cells. These pathways are critical in maintaining lipid balance and influencing lipoprotein metabolism. ACAT1's enzymatic activity impacts how cells manage cholesterol influx and storage linking to broader lipid regulation networks.

ACAT1 is associated with atherosclerosis and Alzheimer's disease. The conversion of cholesterol into cholesteryl esters affects the development of atherosclerotic plaques contributing to cardiovascular disease risk. In Alzheimer's disease ACAT1 may influence the accumulation of amyloid-beta a protein linked to the pathology of the disease. The protein APP (amyloid precursor protein) connects to ACAT1 as disturbances in cholesterol metabolism can affect amyloid-beta production linking this enzyme to neurodegenerative conditions.

Target data

This is one of the enzymes that catalyzes the last step of the mitochondrial beta-oxidation pathway, an aerobic process breaking down fatty acids into acetyl-CoA (PubMed : 1715688, PubMed : 7728148, PubMed : 9744475). Using free coenzyme A/CoA, catalyzes the thiolytic cleavage of medium- to long-chain 3-oxoacyl-CoAs into acetyl-CoA and a fatty acyl-CoA shortened by two carbon atoms (PubMed : 1715688, PubMed : 7728148, PubMed : 9744475). The activity of the enzyme is reversible and it can also catalyze the condensation of two acetyl-CoA molecules into acetoacetyl-CoA (PubMed : 17371050). Thereby, it plays a major role in ketone body metabolism (PubMed : 1715688, PubMed : 17371050, PubMed : 7728148, PubMed : 9744475).
