Abstract excerpt
Substrate specificity of SCF E3 ubiquitin ligases is thought to be determined by the F box protein subunit. Another component of SCF complexes is provided by members of the Roc1/Rbx1/Hrt1 gene family, which encode RING-H2 proteins. Drosophila contains three members of this gene family. We show that Roc1a mutant cells fail to proliferate. Further, while the F box protein Slimb is required for Cubitus interruptus...
