Recombinant Proteins
Recombinant human TREX1 protein, also known as DNase III, is a 33 kDa protein that plays a crucial role in the regulation of the immune response and DNA metabolism. This protein is encoded by the TREX1 gene and is highly conserved among mammals, with 99% similarity between human and mouse sequences. Recombinant human TREX1 protein has been extensively studied and has shown promising potential in various applications, making it a valuable tool for scientific research.
The recombinant human TREX1 protein is composed of 293 amino acids and has a predicted molecular weight of 33 kDa. It belongs to the DNase III family and contains a conserved DNase domain, which is responsible for its enzymatic activity. The protein also has a nuclear localization signal and a C-terminal domain that is involved in protein-protein interactions. Recombinant human TREX1 protein is expressed in E. coli and purified using chromatography techniques, resulting in a highly pure and active protein.
Recombinant human TREX1 protein is a 3′-5′ exonuclease that plays a vital role in the degradation of single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA). It has been shown to have a preference for DNA with a 3′-OH end, making it an essential enzyme in the regulation of DNA metabolism. This protein is also involved in the clearance of DNA from apoptotic cells, preventing the activation of the immune system and the development of autoimmune diseases. Additionally, recombinant human TREX1 protein has been shown to have antiviral activity, inhibiting the replication of viruses such as HIV and hepatitis B.
Recombinant human TREX1 protein has various applications in scientific research, including its use as an antigen in the development of diagnostic assays and vaccines. Its ability to degrade DNA makes it a valuable tool in the detection of DNA damage and the study of DNA repair mechanisms. This protein has also been studied for its potential therapeutic use in autoimmune diseases, as its deficiency has been linked to the development of systemic lupus erythematosus (SLE) and Aicardi-Goutières syndrome (AGS).
In addition, recombinant human TREX1 protein has been used in the development of novel cancer therapies. It has been shown to have a crucial role in the regulation of the immune response against cancer cells, making it a potential target for immunotherapy. Furthermore, its antiviral activity has sparked interest in using this protein as a therapeutic agent against viral infections.
In summary, recombinant human TREX1 protein is a versatile and essential protein in scientific research. Its structure, activity, and applications make it a valuable tool in various fields, including immunology, DNA metabolism, and cancer research. With further studies and advancements in recombinant protein technology, the potential of this protein in both diagnostic and therapeutic applications is promising.
