Summary: Enables carnitine O-palmitoyltransferase activity and identical protein binding activity. Involved in several processes, including fatty acid metabolic process; liver regeneration; and response to tetrachloromethane. Located in mitochondrial outer membrane. Biomarker of alcoholic hepatitis; end stage renal disease; metabolic dysfunction-associated steatohepatitis; obesity; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in carnitine palmitoyltransferase I deficiency and lipid metabolism disorder. Orthologous to human CPT1A (carnitine palmitoyltransferase 1A).

CPT1a downregulation protects against 7-ketocholesterol-induced fibrosis in tubular epithelial cells by downregulating TGF-beta1, alpha- SMA and NLRP3.

A significant up-regulation of Cpt1a, Acadl and Sirt3, all beta-oxidation genes, along with a significant deacetylation of the forkhead transcription factor 3a (FOXO3A) was found in alpha-LA-treated animals.
Title: Impact of dietary lipoic acid supplementation on liver mitochondrial bioenergetics and oxidative status on normally fed Wistar rats.
dietary fat elevates hepatic Cpt1a expression via a highly coordinated transcriptional mechanism involving increased H3K4Me2, reduced DNAMe, and recruitment of C/EBPbeta, PPARalpha, PGC1alpha, and BAF60a to the gene.

Furthermore, given the already low abundance of Cpt1b in white adipose tissue, it is unlikely that decreases in its expression can quantitatively decrease whole body energy expenditure enough to contribute to an obese phenotype.
Title: Examination of carnitine palmitoyltransferase 1 abundance in white adipose tissue: implications in obesity research.
e found that CPT1AM-expressing rBA have increased FAO, lipolysis, UCP1 protein levels and mitochondrial activity. Additionally, enhanced FAO reduced the palmitate-induced increase in triglyceride content and the expression of obese and inflammatory markers. Thus, CPT1AM-expressing rBA had enhanced fat-burning capacity and improved lipid-induced derangements.

Fructose feeding significantly decreased mRNA levels for PPAR alpha and CPT1A.
Title: High fructose consumption induces DNA methylation at PPARα and CPT1A promoter regions in the rat liver.
Tau supplementation prevented obesity and hepatic TG deposition by upregulating MTP mRNA, ameliorating hepatic lipid efflux, and consequently enhancing PPAR-alpha which increases lipid oxidation through ACO and CPT-1a gene expressions.

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.
