Summary: Summary:This gene is a member of a small family of acyl coenzyme A:cholesterol acyltransferases. The gene encodes a membrane-bound enzyme localized in the endoplasmic reticulum that produces intracellular cholesterol esters from long-chain fatty acyl CoA and cholesterol. The cholesterol esters are then stored as cytoplasmic lipid droplets inside the cell. The enzyme is implicated in cholesterol absorption in the intestine and in the assembly and secretion of apolipoprotein B-containing lipoproteins such as very low density lipoprotein (VLDL). Several alternatively spliced transcript variants of this gene have been described, but their full-length nature is not known. [provided by RefSeq, Jul 2008]
Annotation information: Note: ACAT2 (Gene ID: 39) and SOAT2 (Gene ID: 8435) share the ACAT2 symbol/alias in common. ACAT2 is a widely used alternative name for sterol O-acyltransferase 2 (SOAT2), which can be confused with acetyl-CoA acetyltransferase 2 (ACAT2). [20 Jun 2018]; Note: ACAT2 (GeneID 39) and SOAT2 (GeneID 8435) loci share the ACAT2 symbol/alias in common. ACAT2 is widely used alternative name for acyl-Coenzyme A: cholesterol acyltransferase 2 (SOAT2) conflicting with the official symbol for acetyl-Coenzyme A acetyltransferase 2 (acetoacetyl Coenzyme A thiolase) (ACAT2).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
