Summary
Enables carnitine O-octanoyltransferase activity. Involved in carnitine metabolic process; coenzyme A metabolic process; and fatty acid metabolic process. Acts upstream of or within fatty acid transport. Located in peroxisome. Is expressed in several structures, including brain; ganglia; gut; liver; and spleen. Orthologous to human CROT (carnitine O-octanoyltransferase). [provided by Alliance of Genome Resources, Apr 2025]
Expression
Broad expression in liver adult (RPKM 39.3), liver E18 (RPKM 15.1) and 23 other tissues See more

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.
