LacI repressor tagged with yBFP and a VP16 activation domain
This is the LacI repressor from E.coli tagged with yeast codon optimized BFP and a VP16 activation domain. LacI will bind with high specificity to the the operator lacO and is inhibited in the presence of IPTG. (1) BFP is a monomeric fluorescent protein that has an excitation peak of 399 nm and an emission peak of 465 nm (2). It was yeast codon optimized through DNA synthesis for the purpose of expressing in S. cerevisiae tagged to various repressors and activators. VP16 is a transcription activation domain from the herpes simplex virus that will initiate transcription when fused to a repressor protein. (3)
