Protein

Sterol O-acyltransferase 2

Gene

SOAT2

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

Plays a role in lipoprotein assembly and dietary cholesterol absorption. In addition to its acyltransferase activity, it may act as a ligase. May provide cholesteryl esters for lipoprotein secretion from hepatocytes and intestinal mucosa.

Catalytic activityi

Acyl-CoA + cholesterol = CoA + cholesterol ester.
