ALDH1L1 encodes the human gene, Aldehyde dehydrogenase 1 family member L1. It may also be known as: Cytosolic 10-formyltetrahydrofolate dehydrogenase; 10-FTHFDH; Aldehyde dehydrogenase family 1 member L1; FDH; 10-fTHF; FTHFD; aldehyde dehydrogenase 1 family, member L1. The encoded protein is an enzyme with an amino acid length of 902 and a mass of 98.8 kDa. Other isoforms may exist. ALDH1L1 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.
