TetR CFP

A Tet Repressor tagged with CFP. TetR binds to the tet operator to prevent the transcription of a downstream gene. Repression is relieved by tetracycline.

Usage and Biology

TetR functions as a homodimer to bind tet operator sequences and prevent the association of RNA polymerase with its promoter. Each TetR monomer has a DNA binding domain and a dimerisation domain. The DNA binding domain is a helix-turn-helix motif that associates with a tet operator sequence (TCCCTATCAGTGATAGAGA). Our complementary part, BBa_K2450301, contains 2 repeats of this sequence - one for each monomer.

CFP is a variation on Green Fluorescent Protein.
