ACE_T-CD4 chimeric proteins not transported to the cell-surface

N-terminal region	C-terminal region
ACET 1–342	CD4352–435
ACET 1–426	CD4352–435
ACET 1–536	CD4352–435
CD41–97	ACET 343–737
CD41–187	ACET 427–737
CD41–277	ACET 537–737

Absence of surface immunofluorescence was taken as an index for lack of transport to the cell surface.
