SLC35F2

High affinity plasma membrane importer of the nucleobase queuine (q) and its nucleoside queuosine (Q), two bacterially derived micronutrients acquired from the gut microbiome and diet. Following cellular uptake, queuosine is incorporated at the wobble base (position 34) of tRNAs that decode histidine, tyrosine, aspartate, and asparagine codons, which is important for efficient translation. Also involved in choline transport, although the underlying transport mechanism remains to be elucidated..
