    Snippet: Gml was not transported to the plasma membrane, however. Indirect immunofluorescence microscopy demonstrated that Gml was absent from the cell surface but present in a juxtanuclear region consistent with Golgi localization (Fig . 2 ) . In addition, the two N-linked oligosaccharides added to Gml were not processed to an endo H-resistant form as they 23 were on wild-type G protein. After a 10 min pulse label, wild-type G protein became endo H resi.....
    Document: Gml was not transported to the plasma membrane, however. Indirect immunofluorescence microscopy demonstrated that Gml was absent from the cell surface but present in a juxtanuclear region consistent with Golgi localization (Fig . 2 ) . In addition, the two N-linked oligosaccharides added to Gml were not processed to an endo H-resistant form as they 23 were on wild-type G protein. After a 10 min pulse label, wild-type G protein became endo H resistant with a halftime of about 20 min, whereas Gml was endo H sensitive even after 4 h of chase (see Fig. 10 ). This suggested that the Gml protein was retained in a pre-medial Golgi compartment, like the wild-type El protein .
