CATCHFIRE AT A GLANCE
CATCHFIRE, the only self-reporting protein dimerizer
CATCHFIRE of The Twinkle Factory is a fluorogenic chemically induced dimerization technology. In other words, the brandnew self-reporting protein dimerizer! It indeed enables to artificially control the proximity of two proteins in cells, while visualizing their interaction. First, the two proteins of interest are genetically fused to two small protein domains, FIREmate and FIREtag. Then, a cognate fluorogenic molecular glue of the “match” family, e.g., match550, induces their interaction. As a result, when the two domains interact, the fluorescence of match550 measured at 550 nm increases 100-fold. This hence enables to see the newly induced interaction by fluorescence microscopy. Furthermore, the ternary interaction is reversible, making CATCHFIRE the first-ever self-reporting reversible dimerizer system!

Combining reversibility and self-reporting, featuring a very small footprint (FIREtag is 10-aa heavy only), CATCHFIRE hence paves the way to a multitude of applications in cell biology and drug discovery. HELP YOURSELF!!!
