Oatp2bl Slco2bl Oatp-9/moatl /oatp-B Slc21al0 

Only a few of the Oatps/OATPs identified so far have been characterized in detail on the functional, structural, and genomic levels. Despite the fact that a larger number of endogenous compounds are known to be transported by the Oatps/ OATPs, little is known about the in vivo physiological importance of these transporters. The exact transport mechanism(s) of the OATPs has not yet been worked out. However, studies with rat Oatps suggest that they act as organic anion exchangers [1].
