Predicted to enable L-phosphoserine phosphatase activity; magnesium ion binding activity; and protein homodimerization activity. Acts upstream of or within in utero embryonic development. Predicted to be located in neuron projection. Predicted to be active in cytoplasm. Is expressed in several structures, including alimentary system; brain; integumental system; liver; and urinary system. Human ortholog(s) of this gene implicated in PSPH deficiency. Orthologous to human PSPH (phosphoserine phosphatase). [provided by Alliance of Genome Resources, Apr 2022]
