2.A.60.1.9
Oat12 (SLC21A12) (transports bile salts, hormones (T3) and eicosanoids (prostaglandin E2)). It has 722 aas and 12 TMSs.  There is an interplay of OATP1A/1B/2B1 uptake transporters and ABCB1 and ABCG2 efflux transporters in the handling of bilirubin and drugs (Li et al. 2024).  The SLCO4A1-mediated transmembrane transport of lysionotin attenuates acute lung injury through activating the AMPK/Nrf2 signaling pathway (Xiong et al. 2025).
