Overview on HA constructs and synthetic peptides. (A and B) Rhodamine (TAMRA) labeled full length HA (A, Rh-HA) or synthetic peptide (TMD-peptide) corresponding to the transmembrane domain of influenza HA (B, Rh-TMD) were incorporated into GUVs of different lipid compositions. (C and D) Full length HA tagged C-terminally with Cer (C, HA-Cer) or a HA fragment linked N-terminally to YFP and signal peptide (SP) (D, TMD-HA-YFP) were expressed in the plasma membrane of CHO-K1 cells. GPMVs were generated subsequently and used for confocal scanning microscopy. Rh, TAMRA. ∗Palmitoylation site.
