Also known as FLJ20920ACSMW
Summary
ACSF2 (acyl-CoA synthetase family member 2, HGNC:26101) is a protein-coding gene on chromosome 17q21.33, encoding Medium-chain acyl-CoA ligase ACSF2, mitochondrial (Q96CM8). Acyl-CoA synthases catalyze the initial reaction in fatty acid metabolism, by forming a thioester with CoA.
Enables medium-chain fatty acid-CoA ligase activity. Predicted to be involved in fatty acid metabolic process. Located in mitochondrion.
