The function of Ensembl gene identifier ENSG00000157600 (TMEM164, transmembrane protein 164) is as follows. Positive regulator of ferroptosis (PubMed:35947500, PubMed:36782012). Involved in the acylation of ether lysophospholipids with the arachidonoyl chain (5Z,8Z,11Z,14Z-eicosatetraenoyl; C20:4) of diacylglycerophospholipids, generating C20:4 ether glycerophospholipids (ePEs) such as 1-(1Z-octadecenyl)-2-(5Z,8Z,11Z,14Z-eicosatetraenoyl)- sn-glycero-3-phosphoethanolamine (PE (P-18:0/20:4)), which promotes ferroptosis (PubMed:36782012). Selectively mediates ATG5-dependent autophagosome formation during ferroptosis, rather than during starvation, and regulates the degradation of ferritin, GPX4 and lipid droplets to increase iron accumulation and lipid peroxidation, thereby promoting ferroptotic cell death (PubMed:35947500). .
