Abstract excerpt
Monocarboxylate transporter 8 (MCT8) facilitates cellular influx and efflux of the thyroid hormones (THs) T(4) and T(3). Mutations in MCT8 lead to severe psychomotor retardation. Here, we studied the importance of 2 highly conserved residues (Arg445 in transmembrane domain 8 and Asp498 in transmembrane domain 10) for substrate recognition and helix interactions. We introduced single and double mutations (R445A,...
