AXIN2, or axin inhibition protein 2, is a gene that plays a crucial role as a negative regulator of the Wnt signaling pathway, which is involved in cell development and cancer. The AXIN2 Promoter luciferase reporter vector is designed for studying the regulation of AXIN2. The vector contains the AXIN2 promoter region upstream of a firefly luciferase reporter gene, which can specifically report activity for AXIN2 activity.
