In sec13-1 mutants, Gap1p exits the ER but is not transported to the plasma membrane. (A) Wild-type (CKY465) and sec13-1 (CKY466) strains expressing Gap1p-HA were grown in ammonia medium at 24°C, and cell lysates were fractionated on density gradients of 20–60% sucrose containing 10 mM EDTA. Gap1p-HA and markers for different subcellular compartments were evaluated for each fraction as described in Fig. 3. (B) Wild-type (CKY465) and sec13-1 (CKY466) strains expressing Gap1p-HA were grown in ammonia medium at 24°C, and cell lysates were fractionated on density gradients of 20–60% sucrose containing 1 mM Mg2+.
