Summary: Enables D-glucose binding activity; dehydroascorbic acid transmembrane transporter activity; and hexose transmembrane transporter activity. Involved in D-glucose transmembrane transport; dehydroascorbic acid transport; and fructose transmembrane transport. Acts upstream of or within insulin receptor signaling pathway and response to hypoxia. Located in plasma membrane. Is expressed in several structures, including adipose tissue; gut; liver; placenta; and spleen. Orthologous to human SLC2A8 (solute carrier family 2 member 8).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
