Properties of the NH2-terminal domain of Pep12p. (A) GFP-tagged PNTP and the F20L mutant version both reach vacuoles in wild-type cells. PNTS, the equivalent construct with the Sso1 TMD, goes to vacuoles in wild-type and end4 cells, whereas the F20L mutant goes to the plasma membrane. (B) GFP-labeled derivatives of Ste18p (as diagrammed) were expressed in a Δste18 strain and imaged. Equivalent constructs without GFP, or no construct (−), were expressed in Δste18 cells carrying a FUS1-lacZ reporter and the cells assayed for β-galactosidase activity. Note the log scale of the graph.
