Synonyms C6orf29; CTL4; DFNA72; NG22; SLC44A4; Solute carrier family 44 member 4; TPPT; TPPT1; Thiamine pyrophosphate transporter 1; hTPPT1
DT Family Choline Transporter-Like (CTl) Family ;
Tissue Specificity Highly expressed in colon, also detected inprostate, trachea and lung (PubMed:24379411). Isoform 3 is alsoexpressed in colon but a lower levels (PubMed:24379411).
Function This transporter mediates the transport of choline and plays a role in the choline-acetylcholine system and is required to the efferent innervation of hair cells in the olivocochlear bundle for the maintenance of physiological function of outer hair cells and the protection of hair cells from acoustic injury. Also described as a thiamine pyrophosphate transporter in colon, may mediate the absorption of microbiota-generated thiamine pyrophosphate and contribute to host thiamine (vitamin B1) homeostasis.
Disease(s) Vitamin B1 deficiency [ICD-11: 5B5A]
Endogenous Substrate(s) Thiamine
