Carnitine palmitoyltransferase 1B (CPT1B) also known as CPT1-M is an enzyme important for fatty acid metabolism. This protein has a molecular weight of about 88 kDa. It is expressed mainly in skeletal muscle tissue and heart. CPT1B is involved in the transport of long-chain fatty acids into the mitochondria which is necessary for beta-oxidation an important metabolic process where fatty acids are broken down to generate energy.

Biological function summary

CPT1B serves an important role in energy metabolism by enabling the conversion of fatty acids into energy within muscle cells. This protein functions as part of the carnitine shuttle complex in conjunction with carnitine-acylcarnitine translocase (CACT) and carnitine palmitoyltransferase 2 (CPT2). This system collectively facilitates the translocation of fatty acids into the mitochondria for subsequent breakdown and energy production.

Pathways

CPT1B plays a role in fatty acid oxidation and energy metabolism pathways. It helps regulate the balance of energy production by modulating the entry of fatty acids into mitochondria. In these pathways CPT1B interacts with CPT2 and CACT ensuring efficient fatty acid transport and oxidation. Through these interactions it helps maintain energy homeostasis especially in tissues with high metabolic demands like muscle and heart.

CPT1B has associations with metabolic conditions such as obesity and insulin resistance. When CPT1B function is impaired it can lead to inefficient fatty acid metabolism contributing to lipid accumulation and metabolic dysfunction. Also connections exist between CPT1B activity and symptoms of metabolic syndrome where alterations in CPT1B expression may impact energy utilization and fat storage in muscle tissue.
