Summary
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. [provided by RefSeq, Nov 2011]
Annotation information
Note: ACAT1 (Gene ID: 38) and SOAT1 (Gene ID: 6646) share the ACAT1 symbol/alias in common. ACAT1 is a widely used alternative name for sterol O-acyltransferase 1 (SOAT1), which can be confused with the official symbol for ACAT1 (acetyl-CoA acetyltransferase 1, GeneID 38). [01 Jun 2018]

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.

    Description
    Transcript Variant: This variant (2) lacks an internal exon in the 5' region compared to variant 1. This results in translation initiation from an alternative, downstream start codon, and an isoform (2) with a shorter and distinct N-terminus compared to isoform 1.

RNA

    Status: REVIEWED

    Description
    Transcript Variant: This variant (4) lacks two consecutive exons in the 5' region, and uses an alternate acceptor splice site at an internal exon compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 3, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
