Rlg1 proteins interact with polysomes irrespective of existence of HAC1 mRNAs. (A) FLAG-AtRlg1p and FLAG-ScRlg1p were immunoprecipitated with anti-FLAG M2 agarose and eluted from the resin by incubating with a 3×FLAG peptide. The eluates were loaded onto a 16/50% step sucrose density gradient as in Figure 7B. (B–E) Extracts were prepared from HA-ScRLG1 HAC1 (B), HA-ScRLG1 hac1Δ (C), HA-AtRLG1[M74] HAC1 (D), and HA-AtRLG1[M74] hac1Δ (E) and sedimented through a 10–50% sucrose density gradient as in Figure 4. The fractions were subjected to Western blotting with an anti-HA antibody. In F and G, wild-type (W303-1A) and hac1Δ (TMSC09) strains with the authentic RLG1 on their chromosome were analyzed as above, and ScRlg1p in the fractions was detected with anti-Rlg1p antibodies.
