Part:BBa_K642006

cI repressor tagged with yBFP and a VP16 activation domain

This is the cI repressor from phage lambda tagged with yeast codon optimized BFP and a VP16 activation domain. cI will bind to two operators already present in the registry: BBa_R0051 & BBa_K105021. BFP is a monomeric fluorescent protein that has an excitation peak of 399 nm and an emission peak of 465 nm (1). 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. (2)
