FIGURE 7:

Grp170 promotes degradation of a nonglycosylated ERAD-Ls substrate. (A) Cells expressing TTR D18G-HA and transfected with scrambled,Grp170 siRNA (#1 or #2), or Sil1 siRNA (#1 or #2) were treated with cycloheximide for the indicated time and harvested, and the resulting WCE analyzed with an anti-HA antibody. (B, C) The TTR D18G-HA band intensity in A was quantified as in Figure 5C. (D) Top, parental Flp-In T-REx 293 cells were transfected with either scrambled or Grp170 siRNA #1. Where indicated, cells transfected with Grp170 siRNA #1 also stably expressed either siRNA-resistant WT Grp170-FLAG or G41L Grp170-FLAG. After siRNA transfection, cells were transfected with TTR D18G-HA, treated with cyclohexamide for the indicated time, and harvested, and the resulting WCE was analyzed as in A. Bottom, as for the top, except that cells stably expressing FLAG-Sil1 were used. (E) As in A, except that CD3d-YFP was used.
