Protein of unknown function DUF829. Contains exclusively eukaryote proteins including transmembrane protein 53. Said to be integral membrane proteins (!?) Dictyostelium discoideum Net4 (dicdi-q54yr8), which has strong homologies to mammalian DUF829/Tmem53/NET4 is found on lipid droplets (Du et al.). Seems to have a conserved catalytic triad Ser-113, Asp-220, and His-252 in TMEM53_HUMAN
