... overexpression of ET B R in HEK293 cells. In addition, because most of the ET B R at the cell surface is localized in nonlipid raft membranes, the constitutive trafficking of ET B Rfrom nonlipid raft ... from endothelial cells [1,2] might be regulated by interactions with caveolins, in addition to the rapid desensitization/internal- ization of ET B R [9–11]. The colocalization and c...
