Figure 8. WDR5a Associates with Multiple Putative H3K4 Methyltransferases.
(A) Interaction of WDR5a with SDG14 in yeast. Full-length WDR5a and SDG14 proteins were respectively fused with the GAL4 AD and BD domains. Yeast cells harboring these fusions, AD and/or BD, as indicated, were grown on the highly selective SD media lacking of Trp, Leu, His and adenine. (B) Physical interaction of WDR5a-cEYFP with nEYFP-SDG14 in onion epidermal cells as analyzed by BiFC. Yellowish-green signal indicates the binding of WDR5a-cEYFP with nEYFP-SDG14 in the nuclei. Blue DAPI staining indicates nuclei. Bar = 20 µm. (C)Association of WDR5a with SDG16 in yeast. Full-length WDR5a and SDG16 proteins were respectively fused with the GAL4 AD and BD domains. (D) Physical interaction of WDR5a-cEYFP with nEYFP-SDG16 in onion epidermal cells analyzed by BiFC. Yellowish-green signal indicates the binding of WDR5a-cEYFP with nEYFP-SDG16 in the nuclei. Bar = 20 µm.
