Gene ID
UniProt ID
DT Family Organo Anion Transporter (OAT) Family ;
Tissue Specificity Highly expressed in brain and in Leydig cellsin testis. Detected in many brain regions with the exception ofpons and cerebellum. Not strongly enriched in cerebralmicrovessels.
Function This Na(+)-independent transporter mediates the organic anions such as the thyroid hormones thyroxine (T4) and rT3 and may play a signifiant role in regulating T4 flux into and out of the brain. Other potential substrates, such as triiodothyronine (T3), 17-beta-glucuronosyl estradiol, estrone-3-sulfate and sulfobromophthalein (BSP) are transported with much lower efficiency.
