B-arrestin:TEV Protease GB compatible with B2-B5

Usage And Biology

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 presents in pUPD2 and has overhangs compatible for Golden Braid cloning. The CDS has position B2-B5.
