IHC image of CPT1A staining in human normal kidney formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab128568, 0.5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Supplementary information

CPT1A also known as carnitine palmitoyltransferase 1A is a vital enzyme involved in the transport of long-chain fatty acids across the mitochondrial membrane. This protein facilitates the conversion of fatty acids into acyl-carnitine a process necessary for beta-oxidation within the mitochondria. The molecular weight of CPT1A is approximately 88 kDa. CPT1A predominantly expresses in liver cells where energy metabolism from fatty acids is important. Alternate names for this target include CPT 1 and CTP1A reflecting its central role in metabolic processes related to lipid utilization.
Biological function summary

CPT1A plays a vital role in energy production by facilitating mitochondrial fatty acid oxidation. It does not function as a solitary enzyme but often associates with other enzymes forming a multiprotein complex that includes acyl-CoA synthetase. This complex enables efficient fatty acid transport and oxidation converting stored fats into usable energy. As CPT1A primarily operates in the liver its activity significantly impacts overall lipid and energy homeostasis demonstrating its critical regulatory role.

Pathways

CPT1A is central to the fatty acid beta-oxidation pathway an important process for breaking down fatty acids to produce energy. This pathway also involves proteins such as CPT1B a related isoform present in muscle tissues. CPT1A's function is important in the liver's capacity to regulate energy balance and respond to metabolic demands. Additionally CPT1A interacts within the signaling pathway of AMPK (AMP-activated protein kinase) which further integrates it into broader metabolic regulation networks linking energy status to cellular function.

CPT1A is notably associated with metabolic syndromes and fatty liver disease. Mutations or deficiencies in CPT1A can lead to disorders like hepatic carnitine palmitoyltransferase 1A deficiency characterized by hypoketotic hypoglycemia and hepatomegaly. Furthermore its dysregulation can impact proteins such as ACC1 (acetyl-CoA carboxylase) in the context of metabolic syndrome. Research continues to explore the implications of CPT1A in non-alcoholic steatohepatitis highlighting its relevance in liver energy metabolism disorders and their pathophysiology.

Target data

Catalyzes the transfer of the acyl group of long-chain fatty acid-CoA conjugates onto carnitine, an essential step for the mitochondrial uptake of long-chain fatty acids and their subsequent beta-oxidation in the mitochondrion (PubMed : 11350182, PubMed : 14517221, PubMed : 16651524, PubMed : 9691089). Also possesses a lysine succinyltransferase activity that can regulate enzymatic activity of substrate proteins such as ENO1 and metabolism independent of its classical carnitine O-palmitoyltransferase activity (PubMed : 29425493). Plays an important role in hepatic triglyceride metabolism (By similarity). Also plays a role in inducible regulatory T-cell (iTreg) differentiation once activated by butyryl-CoA that antagonizes malonyl-CoA-mediated CPT1A repression (By similarity). Sustains the IFN-I response by recruiting ZDHCC4 to palmitoylate MAVS at the mitochondria leading to MAVS stabilization and activation (PubMed : 38016475). Promotes ROS-induced oxidative stress in liver injury via modulation of NFE2L2 and NLRP3-mediated signaling pathways (By similarity).
