No. Sentence Comment

203 No mature G5 was present in cells expressing G5 with the R389H, R419H, or N437K mutations. Login to comment
204 Trafficking was less efficient in cells expressing the E146Q mutation, and only trace amounts of mature G5 were seen in cells expression G5 with the R419P mutation. Login to comment
213 The appearance of the 150 kDa band was only apparent in cells expressing the G5 mutants E146Q and R419P and correlated with the appearance of fully processed G5 as determined by SDS-PAGE. Login to comment
