The ubiquitous snRNA:U6:96Ac promoter drives expression of a single sgRNA (CAAAGTGATAGTGCATCCAT) that targets Rpn8.
Crispr-Cas9 mutagenesis of Rpn8 by expressing Spyo\Cas9UAS.Tag:NLS(Unk), either under the control of Scer\GAL4GMR71G10 or in the absence of a driver, and using Rpn8gRNA.pCFD3-2 as a guide, results in lethality.
