Overview
L7Ae is an RNA binding protein that represses translation of the targeted transcript. Regulating gene expression on the translational level allows for faster repression of the desired construct than transcriptional repressors. L7Ae targets a specific sequence, called the 2x-kturn, on the 5’ end of the RNA. We use L7Ae to repress constitutive 2x-kturn_eGFP. L7Ae can be used to create more complex genetic circuits that are regulated on both the translational and transcriptional level. By targeting L7Ae to exosomes we create the opportunity for the creation of more intricate feedback looks in receiver cells.
L7Ae Characterization
To demonstrate L7Ae mediated repression, we transfected constitutively L7Ae and constitutive 2x-kturn_eGFP. As we increased the amount of transfected L7Ae, we saw increased repression of GFP expression.
