Design of a viral vector for knocking down Yellow Fluorescent Protein expression (and whatever it is attached to).

Virus will be constructed and produced by the UF Vector Core Lab.

To rescue limited brain regions in the FKO mice, we will construct a rAAV virus which will express a short-hairpin RNA (shRNA) that causes degradation of YFP, using previously published shYFP sequences PMID 16676321 PMID 18708075. PMID 15582578 ( Targeted degradation of the 771-nt YFP portion of a YFP-tagged transgene should be sufficient to block expression of the complete transgene PMID 16676321.

The construct will also contain DsRed or mCherry as the reporter gene to allow co-localization with the constitutive YFP reporter in 14-3-3 FKO mice. A rAAV-DsRed vector without shYFP will be constructed as a control virus.
