A, Relative GCR values in Table 2 are graphically shown. The GCR rate of RDKY3615 (Wt (SLD2)) is set as one. B, RDKY3615 (Wt (SLD2)), YST1336 (sld2-11D), YST1090 (+vector), YST1737 (+SLD2), YST1739 (+sld2-11D), YST1747 (+sic1N-SLD2) and YST1749 (sic1N-sld2-11D) cells were grown (asynchronous), and aliquots of the culture were arrested in G1 or S phase with alpha factor or HU, respectively. Whole cell extracts were prepared and subjected to western blotting. Sld2 proteins were detected with anti-Sld2 antibody. The loading control shows the corresponding region of the Ponceau-S-stained membrane. *: non-specific background band. Lanes 14, 15, 21 and 22 are enlarged to show the Sic1N-Sld2 bands (bottom).
