ALDH1L2 encodes the human gene, Aldehyde dehydrogenase 1 family member L2. It may also be known as: Mitochondrial 10-formyltetrahydrofolate dehydrogenase; Mitochondrial 10-FTHFDH; mtFDH; Aldehyde dehydrogenase family 1 member L2; aldehyde dehydrogenase 1 family, member L2. The encoded protein is an enzyme with an amino acid length of 923 and a mass of 101.7 kDa. Other isoforms may exist. ALDH1L2 is a member of the GART family; Aldehyde dehydrogenase family, ALDH1L subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
