has agent OATPS family (canonical)[Cholestasis] importing anion into hepatocyte vascular side (sinusoidal side) membrane [cholestasis] [Cholestasis] organic anion import into hepatocyte vascular side (sinusoidal side) membrane [Cholestasis] PMID:23907487 Sodium-independent uptake of conjugated and unconjugated bile acids is performed by members of the organic anion-transporting polypeptides (OATPs). OATPs also transport numerous drugs and hepatotoxicants. The sodium-independent movement of the organic anion into hepatocyte vascular side (sinusoidal side) membrane. This entity is a specific course-dependent process. This process can constitute the course of Cholestasis. The sodium-independent portion of bile salt uptake is mediated by OATPs
