WebCLSY1 resembles that of RDR2, and in clsy1 mutants RDR2 is substantially mislocalized. Pol IV localization is also perturbed slightly in clsy1 mutants, suggesting that CLSY1 acts at the interface between Pol IV and RDR2 (FIG. 2, step 2), perhaps facilitating transcription or the transfer of RNA from Pol IV to RDR2 (REF. 24). WebMay 1, 2013 · The analyses revealed that CLSY1 is also associated specifically with Pol IV (Table 1). These results suggest that both DTF1 and CLSY1 are specifically associated with Pol IV but not Pol V. We then performed yeast two-hybrid assays to determine whether DTF1, CLSY1, and RDR2 may directly interact with each other.
