CUP1 yeast inducible promoter with RFC[10] restriction sites removed

The Cup1 promoter enables binding of RNA Polymerase II and the subsequent transcription of downstream DNA to mRNA. It is activated by ACE1, a transcription factor which binds to copper ions. It was previously available as a standalone part as BBa_K945002, produced by Tec-Monterrery’s 2012 iGEM team; however, the original part contained numerous illegal restriction sites preventing its usability in standard biobrick assembly. Hard information of the Greenfield 2011 team’s BBa_K586000 claims the part is the Cup1 regulatory region, but based on the sequence and its twin we believe it to be mislabeled and that it is instead the CupI CDS.

We acquired our starting sequence from the Vicker’s Lab at the Australian Institute for Bioengineering and Nanotechnology via Addgene, subsequently removed or altered bases corresponding to illegal cut sites, added a biobrick prefix and suffix, and finally ordered the unit as a geneblock from IDT.

Information Supplement

Transcription with CUP1 promoter is activated by sequence-specific transcription factors which bind to the CUP1 upstream activating sequence (CUP1 UAS). This sequence contains five binding sites for the Cu²⁺-dependent transcriptional activator ACE1/CUP2. The CUP1 UAS is necessary and sufficient for rapid and robust activation of this transcription.
