MITA Antibody STING1/8129R / Mediator of IRF3 Activation Antibody recognizes STING1, an intracellular signaling protein encoded by the TMEM173 gene. STING1 is also widely known as STING, MITA, ERIS, and MPYS and functions as a central regulator of cytosolic DNA sensing and innate immune signaling. The name MITA, or Mediator of IRF3 activation, reflects the protein's important role in connecting detection of cytosolic DNA with activation of interferon regulatory factor 3 and subsequent type I interferon responses.
STING1 is a major component of the cyclic GMP-AMP synthase (cGAS)-STING pathway. When double-stranded DNA accumulates in the cytosol, cGAS binds the DNA and catalyzes production of the second messenger cyclic GMP-AMP (cGAMP). cGAMP binds directly to STING1, inducing conformational changes and promoting movement of the protein from the endoplasmic reticulum toward Golgi-associated compartments. This trafficking step is integral to downstream STING signaling.
Activated STING1 recruits TANK-binding kinase 1 (TBK1), which phosphorylates IRF3. Activated IRF3 subsequently translocates to the nucleus and promotes transcription of type I interferons and interferon-stimulated genes. Through this mechanism, MITA links intracellular DNA recognition to antiviral and inflammatory responses. STING1 signaling can be initiated by DNA associated with viral or bacterial infection as well as endogenous DNA arising from mitochondrial damage, genomic instability, or other forms of cellular stress.
The biological importance of Mediator of IRF3 Activation extends beyond antimicrobial defense. The cGAS-STING pathway is studied in tumor immunology, autoinflammatory disease, cellular stress, DNA damage responses, and immune surveillance. Both excessive and insufficient STING activity can alter immune homeostasis, making regulation of this pathway an important area of research.
Clone STING1/8129R is a recombinant rabbit monoclonal antibody generated against a human STING1 protein sequence within amino acids 190-290. NSJ Bioreagents offers this MITA Antibody as a clone-defined reagent for investigating STING1 and its role in cytosolic DNA sensing and interferon regulation. A MITA Antibody can support research into innate immunity, IRF3 activation, inflammatory signaling, host defense, and cGAS-STING pathway biology.
For a polyclonal antibody with broader validation across the cGAS-STING signaling pathway, see our STING1 Antibody / cGAS-STING Pathway Antibody page.
Optimal dilution of the MITA Antibody STING1/8129R / Mediator of IRF3 Activation Antibody should be determined by the researcher.
A recombinant partial protein sequence (within amino acids 190-290) from the human protein was used as the immunogen for the MITA antibody.
Aliquot the MITA antibody and store frozen at -20oC or colder. Avoid repeated freeze-thaw cycles.
