Binds medium- and long-chain acyl-CoA esters with high affinity. Can interact in vitro with linoleoyl-CoA and linolenoyl-CoA (PubMed:21128943). Binds phosphatidic acid (PA) and phosphatidylcholine (PC) in vitro. May play a role in the biosynthesis of phospholipids. May be involved in lipid degradation via peroxisomal beta-oxydation (PubMed:24738983). Highly expressed in leaves. Expressed in roots and seeds. Induced by drought stress and wounding. May be due to a competing acceptor splice site. Belongs to the ACBP family.
