Literature-anchored findings (GeneRIF, showing 2)

  • Data show that SLC37A1 and SLC37A2 are endoplasmic reticulum associated, P(i)-linked antiporters, that can transport glucose-6-phosphate. (PMID:21949678)
  • Using both living fish embryos and mammalian macrophages, we show that processing depends on the shrinkage and packaging of phagosomes into a unique cellular compartment, the gastrosome, with distinct molecular and ultra-structural characteristics. Loss of the transporter Slc37a2 blocks phagosomal shrinkage, resulting in the expansion of the gastrosome and the dramatic bloating of the cell. (PMID:30880002)

Alternative names: Solute carrier family 37 member 2

All UniProt accessions (2): Q8TED4, E9PRJ4

UniProt curated annotations — full annotation on UniProt →

Function. Inorganic phosphate and glucose-6-phosphate antiporter. May transport cytoplasmic glucose-6-phosphate into the lumen of the endoplasmic reticulum and translocate inorganic phosphate into the opposite direction. Independent of a lumenal glucose-6-phosphatase. May not play a role in homeostatic regulation of blood glucose levels.

Subcellular location. Endoplasmic reticulum membrane.

Tissue specificity. Detected in intestine and pancreas. Lower expression is also detected in liver and kidney.

Activity regulation. Inhibited by vanadate but not by chlorogenic acid.

Similarity. Belongs to the major facilitator superfamily. Organophosphate:Pi antiporter (OPA) (TC 2.A.1.4) family.
