The function of Ensembl gene identifier ENSG00000240849 (PEDS1, plasmanylethanolamine desaturase 1) is as follows. Plasmanylethanolamine desaturase involved in plasmalogen biogenesis in the endoplasmic reticulum membrane (PubMed:31604315, PubMed:32209662, PubMed:33859415). Plasmalogens are glycerophospholipids with a hydrocarbon chain linked by a vinyl ether bond at the glycerol sn-1 position, and are involved in antioxidative and signaling mechanisms (PubMed:31604315). {ECO:0000269|PubMed:31604315, ECO:0000269|PubMed:32209662, ECO:0000269|PubMed:33859415, ECO:0000303|PubMed:31604315}.
