Fig. 1. Model TA proteins. Sequences of the tail-anchor regions and C-terminal extensions of the polypeptides used in this study. Potential transmembrane (TM) domains are underlined, dots indicate hydrophilic domains extending beyond the sequence presented. Numbers in superscript show the total length of the polypeptides; –TM indicates replacement of the hydrophobic TM domain; G indicates a chimera with a C-terminal N-glycosylation site; OPG indicates a chimera with a C-terminal extension derived from bovine opsin including an N-glycosylation site; N indicates N-glycosylation-target residues.
