Thiamin transporter

WebThiamine is transported into cells by two carriers, THTR1 and THTR2, and deficiency of these results in thiamine-responsive megaloblastic anaemia and biotin-responsive basal ganglia disease respectively. Web9 Jan 2024 · For thiamine to enter the mitochondria, a transporter is needed. Thiamine gets into the mitochondria via a mitochondrial transporter encoded by the SLC25A19 gene. In addition to its role as a cofactor for Krebs cycle enzymes, thiamine also is a cofactor for a key enzyme in the pentose phosphate pathway.
