Enables glycerone-phosphate O-acyltransferase activity. Acts upstream of or within several processes, including cell junction assembly; cerebellum morphogenesis; and ether lipid biosynthetic process. Predicted to be located in mitochondrion and peroxisome. Predicted to be active in mitochondrial membrane and peroxisomal membrane. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Used to study disease of mental health and rhizomelic chondrodysplasia punctata type 2. Human ortholog(s) of this gene implicated in rhizomelic chondrodysplasia punctata type 2. Orthologous to human GNPAT (glyceronephosphate O-acyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
