dao-3 encodes a protein containing tetrahydrofolate dehydrogenase/cyclohydrolase catalytic and NAD(P)-binding domains; by similarity to mammalian enzymes, DAO-3 is predicted to function in one-carbon unit metabolism and thus, in amino acid and nucleotide biosynthesis; dao-3 expression appears to be regulated by daf-2-mediated insulin signaling: microarray experiments suggest that it is upregulated in daf-2 mutant adults, while differential display and Northern analyses suggest that it is down-regulated; a dao-3 promoter gfp fusion is expressed in larvae in the hypodermis and in the nervous system, including tail neurons and phasmids.
Predicted to enable methenyltetrahydrofolate cyclohydrolase activity and methylenetetrahydrofolate dehydrogenase (NADP+) activity. Predicted to be involved in tetrahydrofolate interconversion. Predicted to be located in cytosol. Is an ortholog of human MTHFD2 (methylenetetrahydrofolate dehydrogenase (NADP+ dependent) 2, methenyltetrahydrofolate cyclohydrolase).

Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
