GAS Reporter (Luc) - HeLa Cell Line (IFNgamma/JAK/STAT1 Pathway)

Research Use Only

The GAS reporter (Luc)-HeLa cell line is designed to monitor the activity of interferon gamma-induced signal transduction pathways in cultured cells by measuring activated STAT1 homodimers. It contains a firefly luciferase gene driven by three copies of the interferon gamma-activated sites (GAS) located upstream of the minimal TATA promoter. IFNgamma first binds to a heterodimeric receptor consisting of two chains, IFNGR1 and IFNGR2, causing its dimerization and the activation of specific Janus family kinases (JAK1 and JAK2). Two STAT1 molecules associate with this ligand-activated receptor complex and are activated by phosphorylation to form active homodimer. The active STAT1 homodimers translocate to the nucleus where they bind interferon gamma-activated sites (GAS) in the promoter of IFNgamma inducible genes, including luciferase reporter gene.
