Conventional secretory pathway is not required for Acb1 secretion. (A) Yeast were grown in rich medium at 25°C, washed, and starved for 4 h in acetate buffer at the permissive (25°C) or restrictive temperature (37°C). SDF-2–like activity was determined in the bioassay. The data show an average of three experiments. (B) Cells from A were lysed and Western blotted with anti-Pgk1 and anti-Acb1 antibodies to monitor protein levels at the permissive and nonpermissive temperature.
