TREX1 also known as Three Prime Repair Exonuclease 1 acts as a DNA exonuclease which degrades single-stranded DNA from the 3' end. This protein exhibits a mass of 33 kDa. TREX1's expression is largely found in the cytoplasm of many cell types including those in the immune system and various tissues like the liver spleen and heart. Through its enzymatic activity TREX1 helps maintain genomic stability by processing DNA intermediates that arise from incomplete DNA replication or repair processes.
Biological function summary
TREX1 removes excessive DNA that might trigger immune responses. It is not a part of a large protein complex but works closely with substrates involved in DNA repair and replication. By degrading abnormal DNA TREX1 prevents the initiation of inappropriate immune responses that could result in autoimmunity. Its functionality is essential in preventing the cell from converting these DNA fragments into ligands for DNA sensors which could activate immune signaling pathways.
Pathways
TREX1 plays a significant role in the DNA damage response and innate immune pathways. In the DNA damage response pathway TREX1 functions alongside proteins like ATR and ATM which address DNA replication stress and repair. Within the innate immune pathway it interacts with cGAS (cyclic GMP-AMP synthase) which can become activated in response to cytosolic DNA leading to the production of type I interferons - powerful immune modulators.
Mutations in TREX1 have been linked to autoimmune diseases such as Aicardi-Goutières syndrome and systemic lupus erythematosus. In these conditions the altered or deficient TREX1 leads to the accumulation of DNA in the cytoplasm falsely triggering an antiviral immune response. This relationship with cGAS is critical as the cGAS-STING pathway becomes activated due to the presence of unprocessed DNA resulting in chronic inflammation and contributing to the autoimmune pathology observed in these disorders.
