Inactivation of RAS/cAMP-PKA pathway is required for glucose starvation-induced Hxt1 turnover. (A) Yeast cells (WT) coexpressing Hxt1-GFP in combination with either empty vector or Ras2Val19 were grown as described in Fig. 2A. Membrane fractions were immunoblotted with anti-GFP antibody. (B) Yeast cells (WT and bcy1Δ) expressing Hxt1-GFP were grown as described in Fig. 2A Membrane fractions were immunoblotted with anti-GFP antibody. Actin was served as loading control.
