ParaBAD:RBS- β-arrestin2:TEVp:terminator---pAndersonJ23115:lacO:RBS-eCFP -terminator


Usage and Biology

This part has an inducible promoter from arabinose, leading to a regulated expression of the transcription unit. B-arrestin has the ability to normally bind to the GPCR receptor and facilitate its endocytosis, desensitization or GPCR-independent signaling effects. The second composite of our TANGO system is a fusion of the b-arrestin-2 with the TEV protease.TEV protease recognizes and cleaves the cleavage site. This low proximity allows the TEV protease that is tagged to the βarrestin-2 carrier to cleave its substrate (TCS) .

Design Notes

The coding sequence was domesticated . We removed BsmBI ,BsaI , BtgZI, BpiI sites in order to be compatible with GoldenBraid and MoClo. The sequence is cloned in seva omega2 vector BBa_K3505011and has overhangs compatible for GoldenBraid cloning.
