Background

This gene encodes a five transmembrane protein that functions as a major regulator of the innate immune response to viral and bacterial infections. The encoded protein is a pattern recognition receptor that detects cytosolic nucleic acids and transmits signals that activate type I interferon responses. The encoded protein has also been shown to play a role in apoptotic signaling by associating with type II major histocompatibility complex. Mutations in this gene are the cause of infantile-onset STING-associated vasculopathy. Alternate splicing results in multiple transcript variants.

	Western blotting analysis using anti-TMEM173 antibody (Cat#61113). Total cell lysates (30 μg) from various cell lines were loaded and separated by SDS-PAGE. The blot was incubated with anti-TMEM173 antibody (Cat#61113, 1:5,000) and HRP-conjugated goat anti-rabbit secondary antibody (Cat#201, 1:20,000) respectively. Image was developed using NaQ™ ECL Substrate Kit (Cat#716).
	Western blotting analysis using anti-TMEM173 antibody (Cat#61113). TMEM173 expression in wild type (WT) and STING1 shRNA knockdown (KD) HeLa cells with 20 μg of total cell lysates. Hsp90 α serves as a loading control. The blot was incubated with anti-TMEM173 antibody (Cat#61113, 1:5,000) and HRP-conjugated goat anti-rabbit secondary antibody (Cat#201, 1:20,000) respectively. Image was developed using Plus ECL Super Kit (Cat#636). STING1, Stimulator Of Interferon Response CGAMP Interactor 1.
	Flow cytometric analysis of TMEM173 expression in HT-1080 cells using TMEM173 antibody (Cat#61113, 1:2,000). Green, isotype control; red, TMEM173.
	Immunocytochemical staining of HT-1080 cells with TMEM173 antibody (Cat#61113, 1:1,000). Nuclei were stained blue with DAPI; TMEM173 was stained magenta with Alexa Fluor® 647. Images were taken using Leica stellaris 5. Protein abundance based on laser Intensity and smart gain: Medium. Scale bar: 20 μm.
