Binds medium- and long-chain acyl-CoA esters with high affinity. Can interact in vitro with palmitoyl-CoA, 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 (PubMed:24738983). Highly expressed in leaves. Expressed at low levels in roots and seeds. Induced by salt and drought stresses. Down-regulated by cold stress, wounding and infection with the rice blast fungus Magnaporthe oryzae. Belongs to the ACBP family.
