ISRE Reporter – HEK293 Recombinant Cell Line (JAK pathway)

Catalog #: 60510
Size: 2 vials
The JAK (Janus kinase) /STAT (Signal Transducer and Activator of Transcription) pathway is activated by various cytokines and growth factors and plays a critical role in cell growth, hematopoiesis, and immune response. In mammals, there are four JAKs (JAK1, JAK2, JAK3 and TYK2) and seven STAT proteins. Binding of Interferon alpha (IFNα) to its receptor leads to the activation of JAK1 and TYK2, which in turn phosphorylate and activate STAT1 and STAT2. The phosphorylated STAT1 and 2 form a heterodimer and bind to IRF9/p48, forming a protein complex known as ISGF3. This complex translocates to the nucleus and binds to the ISRE (Interferon Stimulated Response Element) in the promoter region thereby promoting transcription of interferon-inducible genes.

The ISRE Reporter – HEK293 Cell Line is designed for monitoring the activity of the JAK/STAT signaling pathway. The ISRE Reporter – HEK293 Cell Line contains the firefly luciferase gene under the control of ISRE stably integrated into HEK293 cells.
