Glutamine
Glutamine (symbol Gln or Q) is an α-amino acid that is used in the biosynthesis of proteins. Its side chain is similar to that of glutamic acid, except the carboxylic acid group is replaced by an amide. It is classified as a charge-neutral, polar amino acid. It is non-essential and conditionally essential in humans, meaning the body can usually synthesize sufficient amounts of it, but in some instances of stress, the body's demand for glutamine increases, and glutamine must be obtained from the diet. It is encoded by the codons CAA and CAG.
IFFO1
IFFO in human is located on the minus strand at Chromosome 12p13.3. The protein contains 17,709 nucleotide bases that encodes for 570 amino acids. The basal isoelectric point is 4.83. "IFFO1" contains a highly conserved filament domain that spans 299 amino acids from amino residue 230 to 529. This region has been identified as pfam00038 conserved protein domain family. Due to alternative splicing, there are 7 isoforms of IFFO1 in humans with 10 typical coding exons.
