Real-time RT-PCR and Western blot analysis of gene and protein expression in a strain expressing activated CPG-1 (QL1) and the Δcprgs-1 strains ΔRGS-H8, -H15, and -H22. (A) Western blot analysis of CPG-1 protein accumulation. The arrow indicates the bands corresponding to CPG-1. The asterisk indicates a slower-migrating band that cross-reacts with α-CPG-1 antibody (40). Size markers are indicated in kilodaltons. (B) Western blot analysis of CPGB-1 protein accumulation. (C) Transcript accumulation of cprgs-1, cryparin (crp), cpg-1, and cpgb-1 in mutant strains relative to accumulation in the wild-type strain EP155. The arrowhead represents the reference value of 1.0 for EP155, calculated as described in Materials and Methods. Bars represent the standard error for each data set.
