Biological activities of Gas3/PMP22 mutated at the
N-glycosylation site. gas3/PMP22-MG, gas3/PMP22-WT, and
gas3/PMP22-KK were coexpressed with hPLAP in NIH3T3
cells. At different time points after microinjection, cells were fixed
and processed by immunofluorescence to detect hPLAP. Survival and
morphologic changes were scored as described in the text. The data
represent the arithmetic means ± SD of four independent
experiments (altered shape, p < 0.001; survival rate, p <
0.001)
