Scientific Data Images for Human STING/TMEM173 Antibody

Detection of Human STING/TMEM173 antibody by Western Blot.

Detection of Human STING/TMEM173 by Western Blot.

Western blot shows lysates of human peripheral blood lymphocytes (PBL). PVDF Membrane was probed with 1 µg/mL of Human/Mouse STING/TMEM173 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6516) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for STING/TMEM173 at approximately 42 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
Detection of Human STING/TMEM173 antibody by Simple WesternTM.

Detection of Human STING/TMEM173 by Simple WesternTM.

Simple Western lane view shows lysates of HeLa human cervical epithelial carcinoma parental cell line and STING/TMEM173 knockout HeLa cell line (KO), loaded at 0.2 mg/mL. A specific band was detected for STING/TMEM173 at approximately 41 kDa (as indicated) in the parental HeLa cell line, but is not detectable in knockout HeLa cell line. Sheep Anti-Human STING/TMEM173 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6516) was used at 10 µg/mL followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: STING/TMEM173

STING (Stimulator of interferon genes; also ERIS, MPYS, MITA and TMEM173) is a 40-42 kDa 4-transmembrane protein that mediates both antiviral and MHC-II antigen recognition responses. STING is found in the ER, mitochondrial outer membrane and plasma membrane. It acts as an adaptor protein for intracellular viral detection molecules, participating in the induction of type I interferon. It also may play a role in the initiation of apoptosis following MHC-II engagement. Cells known to express STING include B cells, dendritic cells, macrophages, and monocytes. Human STING is 379 amino acids (aa) in length. It contains an N-terminal cytoplasmic region (aa 1-20), four transmembrane segments (aa 21-173), and a C-terminal cytoplasmic domain (aa 174-379). Ubiquitination occurs at Lys150, and phosphorylation occurs at Ser358. STING forms 80 kDa homodimers. There are two potential splice forms, one that shows a 25 aa substitution for aa 1-173, and another that possesses an alternative start site at Met215, coupled to a premature truncation following Arg334. Over aa 215-379, human STING shares 76% aa identity with mouse STING.
