Urate anion transporter 1 (URAT1)

Target
URAT1
Molecular classification
Transporter, Solute carrier family, SLC22A12
01

Overview

Urate anion transporter 1 (URAT1), encoded by the SLC22A12 gene, is a membrane protein predominantly expressed in the proximal tubule of the kidney. It is the principal transporter responsible for mediating the re-absorption of uric acid from the renal filtrate back into circulation. URAT1, along with OAT4 and GLUT9, is central to maintaining serum urate levels. Dysfunction or inhibition of URAT1 can lead to changes in urate balance and contribute to conditions such as gout or kidney disease. Therapeutic inhibition of URAT1 is a key strategy in treating gout and hyperuricemia.
