Tattletales and T-Bow Update 20141018

Tattletales is my concept to multiplex fluorescent protein biosensors ("Tattletales", which is also the overall concept name) and multicolor FP reporters ("T-Bow" for Rainbow T-cells and tumor cells) to study the physiology of live cells.

These are based on:

1. LacI-GFP :: LacO operator synthetic tandem repeat array (Robinett et al 1996 JCB, Fig 4A, http://jcb.rupress.org/content/135/6/1685.full.pdf )

2. the plethora of fluorescent protein biosensors - see page 1 of this "63" download site.

3. the many colors, and combinations of colors (CY11.5, CyPet-YPet 90% FRET, simple color combination fusions, Steven Vogel's "V6" and "V8" …

Tattletales: multiplex fluorescent protein biosensors by spatial localization with TALE-FPs, Cas9-FPs, ZF-FPs, LacI-FPs, TetR-FPs, etc.

T-Bow: Rainbow T-cells and Tumor cells (and ES cells, iPS cells, other cells and organisms). You can think of this as "Brainbow meets TALENs/Cas9/ZFNs/other DNA sequence specific binding proteins".

Big idea: localizing fluorescent proteins - and/or Nano-Lanterns (Take Nagai) - to tandem repeat arrays - is a great way to improve signal to noise ratio compared to the usual …
