STING M284 variant Polyclonal Antibody

Description

Stimulator of interferon genes (STING) is a component of the innate immune response that binds to cyclic dinucleotides, which are bacterial second messengers, leading to activation of NF-κB and transcription of immunomodulatory genes, including type I interferon (IFN). The R284M mutation in STING is associated with constitutive activation of downstream signaling. It increases the propensity of STING to dimerize and associate with the kinase TBK1 , enhancing the ability of STING to activate IRF3 and NF-κB and induce a type I IFN response. However, the R284M mutation occurs outside of the dimerization region between positions 153-177, so rather than a direct effect on dimerization, it is predicted to promote or inhibit binding of a cellular factor that stabilizes or impairs STING dimerization. Cayman’s STING M284 variant Polyclonal Antibody preferentially detects overexpressed STING (R284M) versus wild-type STING by Western blot.
