Fig. 1. Interactions between Ring1B and Mel18. (A) Interaction in yeast cells indicated by the ß-galactosidase activity. Yeast cellswere transformed with the indicated plasmids. Lamin was a negative control. (B) GST pull-down assays. (Part a) Binding of ³⁵S-labeled full-length Mel18 protein (Mel18fl) to GST or GST fused to either full-length or truncated Ring1B (GST-Ring1Bfl, GST-Ring1B ${Delta}$ C or GST-Ring1B ${Delta}$ N, respectively). (Part b) Binding of ³⁵S-labeled full-length Ring1B protein (Ring1Bfl) to GST or GST fused to truncated Mel18 (GST-Mel18 ${Delta}$ PEST) (amino acids 1-233). (Part c) Binding of ³⁵S-labeled truncated Ring1B proteins (Ring1B ${Delta}$ C and Ring1B ${Delta}$ N) to GST or GST-Mel18 ${Delta}$ PEST.
