    Structured Review

    Addgene inc split gal4 components
    (A) The <t>Gal4</t> transcription factor binds to UAS sequences to drive transcription, and can be repressed by the binding of Gal80. Gal4 is drawn here as a monomer, but functions as a dimer in vivo. (B) In the original split-Gal4 system, the <t>Gal4DBD</t> and a strong transcriptional activator (VP16 or <t>p65)</t> are each driven by separate enhancers, and reconstituted in cells by leucine zipper domains. Gal80 cannot bind or repress the split-Gal4 complex. (C) In the split-intein Gal4 system, two fragments of the Gal4 protein, each flanked by a split-intein, are independently driven by separate enhancers, and seamlessly trans-spliced to reconstitute a functional, wildtype Gal4 protein, which can be repressed by Gal80.
    Split Gal4 Components, supplied by Addgene inc, used in various techniques. Bioz Stars score: 92/100, based on 33 PubMed citations. ZERO BIAS - scores, article reviews, protocol conditions and more

    (A) Cartoon schematic of the split-intein GeneSwitch system, not drawn to scale. The same N-terminal fragment of Gal4 used in split-intein Gal4 can be combined with the C-terminus of the GeneSwitch system, which includes amino acids 21-93 of Gal4, a progesterone ligand binding domain (PR-LBD) and the p65 transcriptional activator. (B) Drug-inducible ISC tumor model using the esg -Gal4 N-int ∩ tub- GeneSwitch C-int > UAS: yki S3A . Anterior is up. Scale bar = 50 µm.

    Article Snippet: The inserts for the original split-Gal4 components (pAW-Zip − -Gal4DBD and pAW-p65-Zip + ) were amplified from pBPZpGAL4DBDUw (Addgene 26233) and pBPp65ADZpUw (Addgene 26234), respectively. pCaSpeR-tub-Gal80 was used to test for Gal80 sensitivity in S2R+ cells.
