Summary

SLC35F2 (solute carrier family 35 member F2, HGNC:23615) is a protein-coding gene on chromosome 11q22.3, encoding Queuine/queuosine transporter SLC35F2 (Q8IXU6). 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.

Predicted to enable transmembrane transporter activity. Predicted to be involved in transmembrane transport. Predicted to be located in membrane.

Literature-anchored findings (GeneRIF, showing 6)

  • SLC35F2 was highly expressed in NSCLC tissues and the levels of expression, in particular the levels of the SLC35F2 transcript, were associated with NSCLC pathological staging. (PMID:21874247)
  • Study showed that SLC35F2 was prominently upregulated in papillary thyroid carcinoma (PTC) tissues at both protein and mRNA expression level and significantly associated with lymph node metastasis. These findings suggest that SLC35F2 exerts its oncogenic effect on PTC progression through the mitogen-activated protein kinase pathway, with dependence on activation of TGFBR-1 and apoptosis signal-regulating kinase 1.

Function. 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.

Subcellular location. Cell membrane. Golgi apparatus membrane.

Similarity. Belongs to the SLC35F solute transporter family.
