Acetyl-CoA Carboxylase 2 (ACC2)

Target
ACC2
Molecular classification
Enzyme, Carboxytransferase, Biotin-dependent enzyme
01

Overview

Acetyl-CoA Carboxylase 2 (ACC2) is a biotin-dependent enzyme localized to the outer mitochondrial membrane. It catalyzes the ATP-dependent carboxylation of acetyl-CoA to malonyl-CoA, a key regulatory step in fatty acid metabolism. ACC2 regulates fatty acid oxidation by producing malonyl-CoA, which inhibits carnitine palmitoyltransferase 1 (CPT1), controlling the entry of long-chain fatty acids into mitochondria for β-oxidation. It is predominantly expressed in heart and skeletal muscle, making it a therapeutic target for obesity, metabolic diseases, and cardiac hypertrophy.

02

Mechanism of action

Inhibition of ACC2 to increase fatty acid oxidation by decreasing malonyl-CoA levels, leading to increased CPT1 activity.

03

Biological functions

Fatty acid β-oxidation regulationRegulation of lipid metabolismRegulation of energy production

Disease associations

ObesityMetabolic diseaseCardiac hypertrophy
05

Safety considerations

Knockout studies in mice did not show significant effects on body weight, suggesting potential limitations in therapeutic efficacy.Potential for off-target effects due to structural similarity with ACC1.
