This part is a silencing-form synthetic promoter (SynPro(S)) which can be silenced by its corresponding silencing-form synthetic transcription factor SynTF(S)-43-8. This composite part has two congeners SynPro(S)-43-8;2* (BBa_K2446026) and SynPro(S)-43-8;4* (BBa_K2446027). They differ in the repeat of response elements on SynPro(S).
The SynPro(S)-ZF43-8;8* was designed in this way: it contains two core domains from 5’ end to 3’ end: pSV40, ZF43-8 response elements (ZF43-8REs) in 8 repeats. While SynPro(S)-ZF43-8;2*/4* contains 2 or 4 repeats.
Without the existing of SynTF(S)-43-8, SynPro(S)-ZF43-8;8* can express constantly. While it would be silenced with the existing of SynTF(S)-43-8. The basic expression in constant expression state is high. Meanwhile, it is almost being completely silenced in silencing expression state.
The silencing fold of SynPro(S)-ZF43-8;N* is tunable by choosing different N* RE repeats.
Integrated information about surEGFP posted on Demonstrate page: Wiring orthogonal and tunable SynTF-SynPro repertoire. Or you can alternatively check the (BBa_K2446028) on the Registry of Standard Biological Parts website.
