    Summary
    Enables thiamine transmembrane transporter activity. Involved in thiamine transmembrane transport. Acts upstream of or within thiamine transport. Located in plasma membrane. Is expressed in embryo; liver; and skeletal muscle. Used to study thiamine-responsive megaloblastic anemia syndrome. Human ortholog(s) of this gene implicated in diabetes mellitus; megaloblastic anemia; and thiamine-responsive megaloblastic anemia syndrome. Orthologous to human SLC19A2 (solute carrier family 19 member 2). [provided by Alliance of Genome Resources, Apr 2022]

    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.
