3-Ketoacyl-CoA thiolase, mitochondrial also known as acetyl-Coenzyme A acyltransferase 2 is an enzyme that in humans is encoded by the ACAA2 gene.[5][6]

Acetyl-Coenzyme A acyltransferase 2 is an acetyl-CoA C-acyltransferase enzyme.

Structure

[edit]

The ACAA2 gene encodes a 41.9 kDa protein that is composed of 397 amino acids and contains 88 observed peptides.[7][8]

Function

[edit]

The encoded protein catalyzes the last step of the mitochondrial fatty acid beta oxidation spiral. Unlike most mitochondrial matrix proteins, it contains a non-cleavable amino-terminal targeting signal.[5] ACAA2 has been shown to be a functional BNIP3 binding partner, which provides a possible link between fatty acid metabolism and cell apoptosis.[9]

Clinical significance

[edit]

To date, mutations or variants have not been identified in any clinical diseases. However, the ACAA2 locus has been associated with abnormal blood lipid levels, particularly HDL and LDL cholesterol levels;[10] in addition, this locus has also been correlated with an individual's risk for coronary artery disease.[11]
