Organo-Anion-Transporter (Abk. OATP von englisch Organic Anion Transporting Polypeptide) sind Proteine in der Plasmamembran von Zellen unter anderem der Leber, Nieren und der Blut-Hirn-Schranke, die kΓΆrperfremde Stoffe vom Blut in die Zelle einschleusen. Diese Membrantransporter sind evolutionsbiologisch eng verwandt und kommen hauptsΓ€chlich in Landwirbeltieren und Fischen vor, drei davon sind auch in Insekten zu finden. Ihre Funktion ist die Entfernung von Gallensalzen, Steroidhormonen, Medikamenten und anderen Fremdstoffen aus dem Blut.cite-ref-1[1]cite-ref-2[2]
Vom Menschen sind elf dieser Transporter bekannt. Die Namen der fΓΌr sie codierenden Gene beginnen mit SLCO und die Proteinnamen meist mit OATP (UniProt) oder Oat (TCDB). Nach ihrer Lokalisierung im KΓΆrper gruppiert handelt es sich um
β’ Leber: LST-1 (SLCO1B1), LST-2 (SLCO1B3)
β’ Niere: OATP-H (SLCO4C1)
β’ Gehirn: OATP-A (SLCO1A2), OATP-F (und in Leydig-Zellen, SLCO1C1)
β’ Hoden: OATP-I (SLCO6A1)
β’ ΓΌberall: PGT (SLCO2A1), OATP-B (SLCO2B1), OATP-D (SLCO3A1), OATP-E (SLCO4A1)
β’ unbekannt: OATP-J (SLCO5A1)
