ER stress differentially affects degradation of Asi INMAD substrates.
A, schematic of Asi substrates investigated in this figure. B, cycloheximide chase analysis of yeast of the indicated genotypes expressing Erg11-FLAG or Deg1-Sec62 cultured in the presence of 6 mm DTT, 10 μg/ml tunicamycin, or DMSO for 1 h. C, cycloheximide chase analysis of yeast of the indicated genotypes expressing Vtc1-3HA and Deg1-Sec62 cultured in the absence or presence of 6 mm DTT for 1 h. DTT, tunicamycin, and DMSO were maintained at the same concentration during incubation with cycloheximide. Erg11-FLAG was detected with anti-FLAG antibodies. Vtc1-3HA was detected with anti-HA antibodies. Deg1-Sec62 was detected with peroxidase anti-peroxidase antibodies. Pgk1 served as a loading control. The experiment depicted in B was performed two times. The experiment depicted in C was performed three times (with the exception of tunicamycin treatment, which was performed one time).
