Predicted to enable phosphatidylserine decarboxylase activity. Predicted to be involved in mitochondrial protein catabolic process; phosphatidylethanolamine biosynthetic process; and regulation of mitochondrion organization. Predicted to act upstream of or within lipid metabolic process. Located in mitochondrion. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human PISD (phosphatidylserine decarboxylase). [provided by Alliance of Genome Resources, Apr 2022]
