Analysis of vesicle-mediated trafficking of mrs6 single mutants. The indicated strains in mrs6Δ null cells were prepared and the cultures were labeled with [35S]methionine/cysteine for 20 min, then chased for 5 or 30 min. CPY was immunoprecipitated from extracts derived from each culture. The positions of p1-CPY (ER), p2-CPY (Golgi), and mature (m) CPY (vacuole) are indicated to the left. In wild-type cells incubated at 37°C transport is very rapid. Here, CPY is largely recovered in the mature form, even after a 5-min chase period. B, The distribution of CPY in the p1, p2, and m forms at the 5-min (top) and 30-min (bottom) time points for each mutant were quantitated using densitometry.
