Predicted to enable sphinganine-1-phosphate aldolase activity. Predicted to be involved in sphingolipid catabolic process. Predicted to act upstream of or within carboxylic acid metabolic process. Predicted to be active in endoplasmic reticulum. Is expressed in several structures, including heart; intestine; kidney; liver; and yolk syncytial layer. Human ortholog(s) of this gene implicated in nephrotic syndrome type 14. Orthologous to human SGPL1 (sphingosine-1-phosphate lyase 1).
