A cDNA encoding a novel multispecific organic anion transporter, OAT4, was isolated from a
human kidney cDNA library. The OAT4 cDNA consisted of 2210 base pairs that encoded a
550-amino acid residue protein with 12 putative membrane-spanning domains. The amino
acid sequence of OAT4 showed 38 to 44% identity to those of other members of the OAT
family. Northern blot analysis revealed that OAT4 mRNA is abundantly expressed in the
placenta as well as in the kidney. When expressed in Xenopus oocytes, OAT4 mediated the …
