GARTF, or Phosphoribosylglycinamide formyltransferase, phosphoribosylglycinamide synthetase, phosphoribosylaminoimidazole synthetase, is a human gene encoded by GART. It may also be known as: Trifunctional purine biosynthetic protein adenosine-3; Phosphoribosylamine--glycine ligase; Glycinamide ribonucleotide synthetase; GARS; Phosphoribosylglycinamide synthetase; Phosphoribosylformylglycinamidine cyclo-ligase; AIR synthase; AIRS; Phosphoribosyl-aminoimidazole synthetase; Phosphoribosylglycinamide formyltransferase; 5'-phosphoribosylglycinamide transformylase; GAR transformylase; PGFT; PRGS. The encoded protein is an enzyme with an amino acid length of 1010 and a mass of 107.8 kDa. GARTF is a member of the GARS family; AIR synthase family; GART family. Homologs of this gene exist in other organisms, including: Mouse.
