CC -!- FUNCTION: Catalyzes the transfer of the acyl group of long-chain fatty
CC acid-CoA conjugates onto carnitine, an essential step for the
CC mitochondrial uptake of long-chain fatty acids and their subsequent
CC beta-oxidation in the mitochondrion (PubMed:16169268, PubMed:17030509).
CC Plays an important role in hepatic triglyceride metabolism (By
CC similarity). {ECO:0000250|UniProtKB:P32198,
CC ECO:0000269|PubMed:16169268, ECO:0000269|PubMed:17030509}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-carnitine + hexadecanoyl-CoA = CoA + O-hexadecanoyl-(R)-
CC carnitine; Xref=Rhea:RHEA:12661, ChEBI:CHEBI:16347,
CC ChEBI:CHEBI:17490, ChEBI:CHEBI:57287, ChEBI:CHEBI:57379; EC=2.3.1.21;
CC Evidence={ECO:0000269|PubMed:16169268, ECO:0000269|PubMed:17030509};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:12662;
CC Evidence={ECO:0000305|PubMed:16169268};
CC -!- ACTIVITY REGULATION: Inhibited by malonyl-CoA.
CC {ECO:0000269|PubMed:16169268}.
CC -!- PATHWAY: Lipid metabolism; fatty acid beta-oxidation.
CC -!- SUBUNIT: Homohexamer and homotrimer (By similarity). Identified in a
CC complex that contains at least CPT1A, ACSL1 and VDAC1 (By similarity).
CC Also identified in complexes with ACSL1 and VDAC2 and VDAC3 (By
CC similarity). {ECO:0000250|UniProtKB:P32198}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane
CC {ECO:0000250|UniProtKB:P50416}; Multi-pass membrane protein
CC {ECO:0000255}.
CC -!- DOMAIN: A conformation change in the N-terminal region spanning the
CC first 42 residues plays an important role in the regulation of enzyme
CC activity by malonyl-CoA. {ECO:0000250|UniProtKB:P50416}.
CC -!- DISRUPTION PHENOTYPE: Complete lethality during early embryogenesis.
CC Heterozygous mice are prone to liver steatosis. Compared to wild-type,
CC heterozygotes show minor differences in blood glucose levels and in
CC serum free fatty acid levels after fasting.
CC {ECO:0000269|PubMed:16169268, ECO:0000269|PubMed:22229081}.
CC -!- SIMILARITY: Belongs to the carnitine/choline acetyltransferase family.
CC {ECO:0000305}.
