RESUMO
Indirect fluorescent-antibody studies of living and fixed chick cells infected with temperature-sensitive mutants of Sindbis virus suggest that functional envelope glycoprotein E1 must be inserted through the plasma membrane before E2. PE2 and E2 do not affect the insertion of E1. The experiments also suggest that normal PE2, a glycosylated precursor to E2, reacts with anti-E2 serum; the abnormal PE2 made by a temperature-sensitive PE2 cleavage-defective mutant did not. Abnormal E1 proteins made by E1-defective mutants also failed to react with anti-E1 serum.
