BBa_K511000 1 BBa_K511000 Hef1a-LacOid Promoter MammoBlock 2011-09-24T11:00:00Z 2015-05-08T01:12:31Z 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. false false _674_ 0 6719 9 It's complicated true 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. false Grant Robinson annotation2139540 1 Hef1-alpha Promoter range2139540 1 1 1275 annotation2139541 1 Lac O1 range2139541 1 201 221 annotation2139542 1 Lac Oid range2139542 1 272 291 BBa_K511000_sequence 1 tggctccggtgcccgtcagtgggcagagcgcacatcgcccacagtccccgagaagttggggggaggggtcggcaattgaaccggtgcctagagaaggtggcgcggggtaaactgggaaagtgatgtcgtgtactggctccgcctttttcccgagggtgggggagaaccgtatataagtgcagtagtcgccgtgaagctagaattgtgagcggataacaattccacagtcgaccctaggttgtgtcgcgagtgttggatcccagctgacaccaattgtgagcgctcacaattgctagccgttctttttcgcaacgggtttgccgccagaacacaggtaagtgccgtgtgtggttcccgcgggcctggcctctttacgggttatggcccttgcgtgccttgaattacttccacctggctgcagtacgtgattcttgatcccgagcttcgggttggaagtgggtgggagagttcgaggccttgcgcttaaggagccccttcgcctcgtgcttgagttgaggcctggcctgggcgctggggccgccgcgtgcgaatctggtggcaccttcgcgcctgtctcgctgctttcgataagtctctagccatttaaaatttttgatgacctgctgcgacgctttttttctggcaagatagtcttgtaaatgcgggccaagatctgcacactggtatttcggtttttggggccgcgggcggcgacggggcccgtgcgtcccagcgcacatgttcggcgaggcggggcctgcgagcgcggccaccgagaatcggacgggggtagtctcaagctggccggcctgctctggtgcctggcctcgcgccgccgtgtatcgccccgccctgggcggcaaggctggcccggtcggcaccagttgcgtgagcggaaagatggccgcttcccggccctgctgcagggagctcaaaatggaggacgcggcgctcgggagagcgggcgggtgagtcacccacacaaaggaaaagggcctttccgtcctcagccgtcgcttcatgtgactccacggagtaccgggcgccgtccaggcacctcgattagttctcgagcttttggagtacgtcgtctttaggttggggggaggggttttatgcgatggagtttccccacactgagtgggtggagactgaagttaggccagcttggcacttgatgtaattctccttggaatttgccctttttgagtttggatcttggttcattctcaagcctcagacagtggttcaaagtttttttcttccatttcaggt igem2sbol 1 iGEM to SBOL conversion Conversion of the iGEM parts registry to SBOL2.1 Chris J.
