Summary: Enables carnitine O-palmitoyltransferase activity. Involved in fatty acid beta-oxidation and response to fatty acid. Predicted to be located in nucleolus and nucleoplasm. Predicted to be active in mitochondrion. Human ortholog(s) of this gene implicated in brain disease; lipid metabolism disorder; and muscular disease. Orthologous to human CPT2 (carnitine palmitoyltransferase 2). [provided by Alliance of Genome Resources, Dec 2024]

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.
