Anti-STING1 antibodies are used in the immunodetection of the protein stimulator of interferon response cGAMP interactor 1. In humans, the canonical protein has a reported length of 379 amino acid residues and a mass of 42.2 kDa. It is ubiquitously expressed across many tissue types. A member of the STING protein family, STING1 is known to be involved with innate immune responses. Post-translational modifications have been described, including ubiquitination, sumoylation, palmitoylation and phosphorylation. The STING1 gene has been associated with the disease, STING-associated vasculopathy. Synonyms for this target antigen include N-terminal methionine-proline-tyrosine-serine plasma membrane tetraspanner, endoplasmic reticulum IFN stimulator, endoplasmic reticulum interferon stimulator, and stimulator of interferon genes protein. STING1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
