Recombinant Human Sterol O-acyltransferase 1 (SOAT1), Truncated

Uniprot Id

P35610

Target Species

Human

Target Name

SOAT1

Target Full Name

Sterol O-acyltransferase 1

Target 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) preferentially as susbstrate: shows a higher activity towards an acyl-CoA substrate with a double bond at the delta-9 position (9Z) than towards saturated acyl-CoA or an unsaturated acyl-CoA with a double bond at the delta-7 (7Z) or delta-11 (11Z) positions.

Target Subcellular Location

Endoplasmic reticulum membrane; Multi-pass membrane protein.

Target Protein Families

Membrane-bound acyltransferase family, Sterol o-acyltransferase subfamily

Target Synonyms

SOAT1; ACACT; ACACT1; ACAT; ACAT1; SOAT; STAT; Sterol O-acyltransferase 1; Acyl-coenzyme A:cholesterol acyltransferase 1; ACAT-1; Cholesterol acyltransferase 1

Target Background

The protein encoded by this gene belongs to the acyltransferase family. It is located in the endoplasmic reticulum, and catalyzes the formation of fatty acid-cholesterol esters. This gene has been implicated in the formation of beta-amyloid and atherosclerotic plaques by controlling the equilibrium between free cholesterol and cytoplasmic cholesteryl esters. Alternatively spliced transcript variants have been found for this gene.
