Hef1a-LacOid Promoter MammoBlock

This part encodes a promoter with low-level, constitutive activity that can be repressed by variants of the LacI transcriptional repressor.

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.
