ADAR1 Responsive Luciferase Reporter HEK293 Cell Line

ADAR1 Responsive Luciferase Reporter HEK293 Cell Line is a HEK293 cell line designed to respond to ADAR1 enzymatic activity. These cells were engineered to express an ADAR1 reporter construct comprised of an ADAR1 hairpin target with a stop codon (UAG) susceptible to ADAR1-mediated editing to tryptophan (UUG), located upstream of a firefly luciferase reporter (Figure 1). This cell line has been validated by comparing reporter activation after transfection with ADAR1 and ADAR2. This cell line has been used for the development of the constitutive ADAR1 expressing ADAR1 Activity Luciferase Reporter HEK293 Cell Line (#82239). The ADAR1 reporter construct is compromised of an ADAR1 hairpin targer with a stop codon (UAG) upstream of the sequence encoding luciferase. In the presence of ADAR1 activity, as in the case of transfection with ADAR1, adenine is converted into inosine encoding now the amino acid tryptophan (UUG) and enabling transcription and expression of luciferase. In the absence of transfected ADAR1, luciferase is not transcribed, and the cells show background luciferase activity. Luciferase activity directly correlated with ADAR1 activity.
