Summary
Enables thiamine transmembrane transporter activity. Involved in several processes, including pyridoxine transport; thiamine diphosphate biosynthetic process; and thiamine transmembrane transport. Is active in plasma membrane. Is expressed in several structures, including genitourinary system; heart; liver; lung; and spleen. 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, Nov 2024]

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.
