TMEM173 Antibody (YA6309)

TMEM173 Antibody (YA6309) is a rabbit-derived and non-conjugated IgG monoclonal antibody, targeting to TMEM173. It can be applicated for WB, IHC-P, ICC/IF, IP, ELISA assays, in the background of human, mouse, rat.

The TMEM173 protein acts as a facilitator of innate immune signaling, functioning as a sensor for cytosolic DNA from bacteria and viruses, ultimately promoting the production of type I interferon (IFN-alpha and IFN-beta). This innate immune response is triggered in response to non-CpG double-stranded DNA from viruses and bacteria delivered to the cytoplasm. TMEM173 recognizes and binds cyclic dinucleotides, specifically cyclic di-GMP (c-di-GMP), a second messenger produced by bacteria, and cyclic GMP-AMP (cGAMP), a messenger produced by CGAS in response to DNA virus in the cytosol. Upon binding to c-di-GMP or cGAMP, TMEM173 oligomerizes, translocates from the endoplasmic reticulum, and is phosphorylated by TBK1, leading to the recruitment and activation of the transcription factor IRF3. This induces the expression of type I interferon, establishing a potent anti-viral state. Additionally, TMEM173 plays a direct role in autophagy, with cGAMP-binding initiating ERGIC formation, which serves as the membrane source for autophagosome formation, targeting cytosolic DNA or DNA viruses for lysosomal degradation. The multifaceted activities of TMEM173 highlight its central role in orchestrating innate immune responses and autophagic processes, contributing to the cell's defense against viral and bacterial threats.
