Hef1a-LacOid Promoter MammoBlock

This part is a synthetic promoter formed from the human elongation factor 1a promoter sequence and a LacOid operator that has been computationally shown to bind to the LacI repressor protein more tightly than the wildtype LacO operator.
This part encodes a promoter with low-level, constitutive activity that can be repressed by variants of the LacI transcriptional repressor.
As shown in Figures 1 and 2 below, cotransfection of a construct containing a yellow fluorescent protein (EYFP) driven by the Hef1a-LacO promoter with a construct containing a LacI-KRAB transcriptional repressor driven by the TRE-Tight promoter proves that it is possible to repress Hef1a-LacO expression with the LacI-KRAB LacI variant, which includes a Kruppel-associated box motif previously shown to silence chromatin and thereby inhibit transcription.

When sequencing constructs that include this part, it is important to realize that the Hef1a-LacOid promoter is roughly a kilobase long; therefore, promoter-gene pairs will require either internal sequencing primers or sequencing from the gene side of the construct to be useful.

Repressible LacI Repressor Generator (Hef1a-LacO-LacI) MammoBlock Device
2011-09-27T11:00:00Z
2015-05-08T01:12:31Z
Consult constituent components.
This MammoBlock composite device produces the LacI repressor protein at a low, constitutive level that can be repressed by LacI variants. As a result, this device is expected to either limits its own production constant level or to oscillate; its behavior remains to be interrogated in future experiments.

In order to adhere to the recombination-based MammoBlock standard, and because shipping Biosafety Level 2 mammalian expression vectors to the Registry of Standard Biological Parts is not currently possible, we are providing the sequence resulting from Gateway recombination of the constituent MammoBlock parts here without redistributing the physical DNA plasmids to the Registry. In future years, we hope to make use of improvements in the Registry's accommodations to provide our complete expression vectors.

LacI Repressor MammoBlock

2015-05-08T01:12:31Z
This protein is a mammalian codon-optimized version of the LacI repressor originally derived from Escherichia coli.
This part encodes a repressor protein that binds tightly to the lactose operator originating from Escherichia coli. This protein has been codon-optimized for mammalian expression and is capable of exerting moderate repression on promoters with internal lactose operator sites.
Figures 1 and 2 below show typical levels of repression mediated by the LacI repressor.
