PIP-KRAB-Gal4-VP64

This part is transformed based on the part: PIP_KRAB(BBa_K2446038) of iGEM17_Fudan.The part is one of our synthetic transcription factors (SynTFs) based on 2 parts, PIP-KRAB and Gal4-VP64(BBa_K3132000).Its parental form PIP-KRAB, which was developed by iGEM_Fudan, serves as an inhibitory transcription factor because of the KRAB domain; while the added part Gal4-VP64, an improved part of our team this year, serves as an activating transcription factor because both of the Gal4 and VP64 domain.This is why we call it “bifunctional transcription factor”. PIP-KRAB-Gal4-VP64 contains six core domains from N-terminal to C-terminal: PIP DNA binding domain, nuclear location sequence, KRAB transcription regulating domain, GAL4 DNA binding domain, another nuclear location sequence and VP64 transcription regulating domain[1]. And 2 (G4S) linkers were added between DBD and NLS for providing region flexibility[2]. PIP-DBD and Gal4-DBD enable binding to specific DNA sequences, together with KRAB and VP64 constitute the inhibitory and activating part, respectively. So that we can use it as a bifunctional transcription factor to either activate or repress the expression of our downstream synthetic promoter elements and minimalCMV when binding to specific DNA sequences .
