Figure 2.
α-Factor and Pma1p packaging into vesicles reconstituted with cytosol. Budding assays were performed in duplicates as described in Materials and Methods using donor membranes from lst1Δ, HA-Pma1p-containing cells primed with wild-type cytosol, or lst1Δ cytosol supplemented with Sec23/Lst1p as indicated. Percent packaging of α-factor and Pma1p was determined as described in Materials and Methods and is reported as the mean of at least two independent experiments with error bars indicating SD.
