Predicted to enable cardiolipin synthase activity. Predicted to be involved in cardiolipin biosynthetic process; response to phosphatidylethanolamine; and response to thyroxine. Predicted to act upstream of or within phospholipid biosynthetic process. Located in mitochondrion. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Orthologous to human CRLS1 (cardiolipin synthase 1).
