The function of TMEM86A (transmembrane protein 86A, ENSG00000151117) is as follows. Catalyzes the hydrolysis of the vinyl ether bond of choline or ethanolamine lysoplasmalogens, forming fatty aldehyde and glycerophosphocholine or glycerophosphoethanolamine, respectively and is specific for the sn-2-deacylated (lyso) form of plasmalogen (PubMed:36592658). Plays an important role in lysoplasmalogen metabolism in the adipocyte tissue and macrophages (PubMed:36592658). .
