Figure 1: Diagrams of the eGFP or mRPF-tagged SR-BI and SR-BI-ΔC transgenes. The constructs consist of either SR-BI or SR-BI-ΔC tagged with either eGFP or mRFP on their amino termini. The locations of putative transmembrane domains (TMDs) are also shown. Cytosolic regions are shown in yellow and extracellular regions are shown in blue.
