Part:BBa_K2957045

CMV-2xGal4 (Gal4 repressible promoter), CCL5

Contents:CMV-2xGal4 (Gal4 repressible promoter), CCL5, SynthpA, with Carb resistance

What is it?: A Composite part; it is a genetic circuit with CMV-2xGal4 promoter and CCL5 gene allowing for inducible expression of CCL5.

What does it do?: This part has a promoter that is only active when induced by the syn-notch receptor and was put in our genetic circuits to show inducible production of the CCL5, which is involved in an inflammatory response, we were testing. It was important for our project in particular because of its involvement in the immune system and is known to create neutrophil swarming. This specific part was important to show a wave mechanic since when neutrophils expressing the syn-notch antigen would bind to the receptor on HEK cells, the promoter can activate more or less CCL5 production.

How to use it?: This part was created with Type IIS Cloning and transfected into HEKs. We then were able to test for secretion of CCL5. See more on the Parts Overview Page or MIT iGEM 2019 wiki: <a href=https://2019.igem.org/Team:MIT/Parts>.
