Lack of GTP-bound Rho1p in secretory vesicles of Saccharomyces cerevisiae.

The Journal of cell biology - 7 Jul 2003

Abe Mitsuhiro, Qadota Hiroshi, Hirata Aiko, Ohya Yoshikazu

Abstract excerpt

Rho1p, an essential Rho-type GTPase in Saccharomyces cerevisiae, activates its effectors in the GTP-bound form. Here, we show that Rho1p in secretory vesicles cannot activate 1,3-beta-glucan synthase, a cell wall synthesizing enzyme, during vesicular transport to the plasma membrane. Analyses with an antibody preferentially reacting with the GTP-bound form of Rho1p revealed that Rho1p remains in the inactive form...
