An intact DHHC-CRD is required for PFA3 to function in vacuole fusion. (A) pfa3Δ cells transformed with vector (pRS313), PFA3-2xFlag (pML780), or C134S PFA3-2xFlag (pML782), were grown in selective media, treated with 2 mM DTT, and stained with FM 4–64 before microscopy. Pictures are representative of two independent transformants. Bars, 2 μm. (B) Whole cell lysates (50 μg) from pfa3Δ transformants used in A were probed with α-Flag antibody to detect expression of Pfa3p-2xFlag.
