TRIM5 Protein, Human (N-His)
Based on 1 Customer Validation
The TRIM5 protein is a capsid-specific restriction factor that prevents non-host adapted retroviral infection. TRIM5 acts as a pattern recognition receptor that activates innate immune signaling by triggering E3 ubiquitin ligase activity upon binding to viral capsids. TRIM5 restricts various retroviruses and regulates autophagy. TRIM5 Protein, Human (N-His) is the recombinant human-derived TRIM5 protein, expressed by E. coli , with N-6*His labeled tag.
- Species: Human

Biological Activity
The TRIM5 protein is a capsid-specific restriction factor that prevents non-host adapted retroviral infection. TRIM5 acts as a pattern recognition receptor that activates innate immune signaling by triggering E3 ubiquitin ligase activity upon binding to viral capsids. TRIM5 restricts various retroviruses and regulates autophagy. TRIM5 Protein, Human (N-His) is the recombinant human-derived TRIM5 protein, expressed by E. coli , with N-6*His labeled tag.
TRIM5 is a capsid-specific restriction factor that effectively prevents infection by non-host-adapted retroviruses. Its antiviral activity occurs early in the viral life cycle, specifically after viral entry but before reverse transcription. In addition to its role as a capsid-specific restriction factor, TRIM5 acts as a pattern recognition receptor, activating innate immune signaling in response to the retroviral capsid lattice. Upon binding to the viral capsid, TRIM5 triggers its E3 ubiquitin ligase activity. Teaming up with the UBE2V1-UBE2N complex, it generates 'Lys-63'-linked polyubiquitin chains, facilitating the autophosphorylation of the MAP3K7/TAK1 complex. The activated MAP3K7/TAK1 complex induces NF-kappa-B and MAPK-responsive inflammatory genes, instigating an innate immune response in the infected cell. TRIM5's versatility extends to restricting infections by various retroviruses, including N-tropic murine leukemia virus, equine infectious anemia virus, simian immunodeficiency virus of macaques, feline immunodeficiency virus, and bovine immunodeficiency virus. Moreover, TRIM5 plays a crucial role in regulating autophagy by activating autophagy regulator BECN1 and acting as a selective autophagy receptor, targeting HIV-1 capsid protein p24 for autophagic degradation.

Product Properties
Lyophilized powder.
Lyophilized from a 0.22 μm filtered solution of 50 mM Tris-HCl, 300 mM NaCl, 200 mM arginine, pH 8.0.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
