Invitrogen™ Human STING Control Fragment Recombinant Protein

Description

Highest antigen sequence indentity to the following orthologs: Mouse (76%), Rat (76%). This recombinant protein control fragment may be used for blocking experiments. In IHC/ICC and WB experiments, we recommend a 100x molar excess of the protein fragment control based on the concentration and the molecular weight. Pre-incubate the antibody-protein control fragment mixture for 30 min at room temperature.

STING is a 379 amino acid containing signaling protein that acts as an important component of innate immune signaling. This signaling protein is able to activate both NF-kappa-B and IRF3 transcription pathways to induce expression of type I interferon (IFN-alpha and IFN-beta) and exert a potent anti-viral state following expression. STING may have translocon function, the translocon possibly being able to influence the induction of type I interferons and is also involved in transduction of apoptotic signals via its association with the major histocompatibility complex class II (MHC-II) thus facilitating the detection of intracellular viral RNA species as well as B-form DNA and mediates death signaling via activation of the extracellular signal-regulated kinase (ERK) pathway. Generally seen in endoplasmic reticulum membrane, cell membrane and mitochondrion outer membrane, it is ubiquitously expressed in most of tissues.
