Estes that cannot be duplicated by the Roc1a promoter.Chimeric Roc proteins can function in vivoRecently, Arama et al. showed that a testes-specific Cul3 isoform forms an E3 ligase with Roc1b in the testes, and Roc1b mutant males are sterile because of a failure to complete the late stages of sperm differentiation [37]. Since the BNAR construct displays the same binding specificity as Roc1b, we te
