Part:BBa_K165095

Gli1 bs + LexA bs + mCYC + Zif268-HIV repressor (mCherryx2 tagged) on pRS303

This device constitutes the alpha element in one instance of our limiter construct. It is placed in a mutually inhibitory relationship with the tau element. Under the control of the same promoter as the gene of interest, alpha serves as a readout of its level of induction. In a superthreshold state, it represses tau, allowing R to be expressed and repress G back the threshold level.

The SpeI site is of no consequence, as the utility of parts on pRS vectors is to integrate into the yeast genome.

Usage and Biology

To build a (heretofore untested) limiter, this part should be in a yeast strain with the following constructs:

A) Part:BBa_K165080 pGAL1 + Untagged LexA activator on pRS305
G) Part:BBa_K165078 LexA activable reporter on pRS306

  Into mating type a.  Knock out the Gal2 gene for a tunable level of induction.

R) Part:BBa_K165090 Gli1 bs + LexA bs + mCYC + LexA repressor (mCherryx2 tagged) on pRS306
Alpha) Part:BBa_K165095 Gli1 bs + LexA bs + mCYC + Zif268-HIV repressor (mCherryx2 tagged) on pRS303
Tau) Part:BBa_K165096 Zif268-HIV bs + MET25+ Gli1 repressor (CFPx2 tagged) on pRS304*

  Into mating type alpha. Knock out the Gal2 gene for a tunable level of induction.

Mate the two types, select on SD-His-Trp-Leu-Ura

Inputs: Set the threshold by tuning [Met] between 0 and 500 uM Set the level of induction (A) with Galactose between 0-3%

Outputs expected:
Subthreshold [A]: CFP in the nucleus from Tau, YFP in the cytosol proportionate to subthreshold induction from G being activated by A and not repressed by R.
Superthreshold [A]: mCherry in the nucleus from Alpha and R induction. YFP in cytosol levels out at threshold limit despite rising induction.
