Predicted to enable several functions, including magnesium ion binding activity; methenyltetrahydrofolate cyclohydrolase activity; and methylenetetrahydrofolate dehydrogenase [NAD(P)+] activity. Predicted to be involved in tetrahydrofolate interconversion. Predicted to act upstream of or within one-carbon metabolic process. Located in mitochondrion. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Orthologous to human MTHFD2 (methylenetetrahydrofolate dehydrogenase (NADP+ dependent) 2, methenyltetrahydrofolate cyclohydrolase). [provided by Alliance of Genome Resources, Apr 2022]
