A set of transgenic constructs that each consist of single sgRNA that contains MS2 loops. The tagged sgRNA forms one component of the three-component flySAM (synergistic activation mediator) system, which is designed to produce effective transcriptional activation of the gene targeted by the sgRNA. When crossed to a stock containing the other two components of the flySAM system (a source of nuclease-dead Cas9 fused to a transcriptional activation domain plus an MCP-tagged transcriptional activator), the targeted gene will be overexpressed wherever the three components are expressed together.
