Forkhead box I1 (FOXI1) is a transcription factor that is involved in regulating various aspects of cellular processes, including differentiation, development, and stress responses. The FOXI1 luciferase reporter vector is designed to study the transcriptional activity of FOXI1. The vector contains a FOXI1 DNA consensus binding site and TA minimal promoter upstream of a firefly luciferase reporter gene, which can specifically report FOXI1 activity while maintaining a low basal level of transcription.
