C9orf64 (Chromosome 9 open reading frame 64) is a gene located on chromosome 9, that in humans encodes the protein queuosine salvage protein. The function and biological process of the queuosine salvage protein is a queuosine-nucleotide N-glycosylase/hydrolase (QNG1) that releases queuine from Q-5'-monophosphate, and this activity is required for
