Chemical compound and disease context of TRIM5

 

Biological context of TRIM5

  • The ensuing TRIM5 publication flurry established a paradigm of innate immunity in which the protein lattice of an invading retroviral core, rather than double-stranded RNA or lipopolysaccharide, is recognized by a multimeric, cytoplasmic receptor [12].
  • Importantly, a TRIM5 haplotype containing the nonsynonymous SNP R136Q showed increased frequency among HIV-1-infected subjects relative to exposed seronegative persons, with an odds ratio of 5.49 (95% confidence interval = 1.83 to 16.45; P = 0.002) [13].
  • We sequenced the TRIM5 gene (excluding exon 5) and the 4.8-kb 5' putative regulatory region in genomic DNA from 110 HIV-1-infected subjects and 96 exposed seronegative persons, along with targeted gene sequencing in a further 30 HIV-1-infected individuals [13].
  • Human immunodeficiency virus type 1 (HIV-1) infection is blocked by the alpha isoform of macaque TRIM5 (TRIM5alpha(rh)) or by the product of the owl monkey TRIM5-cyclophilin A gene fusion (TRIMCyp) [14].
  • RNA interference was used to show that endogenous human TRIM5alpha does indeed restrict HIV-1, but the magnitude of this antiviral activity was not altered by disruption of the CA-CypA interaction or by elimination of CypA protein [15].
 

Anatomical context of TRIM5

 

Associations of TRIM5 with chemical compounds

  • Here, we exploit its modular domain organization and cyclosporine sensitivity to probe the kinetics and mechanism of TRIM5-mediated restriction [19].
  • Treatment of cells with geldanamycin, an Hsp90 inhibitor, resulted in disappearance or reduction of the TRIM5alpha-associated cytoplasmic bodies, yet exerted little effect on the restriction of retroviral infection [20].
  • Arsenic trioxide had complex and TRIM5alpha-independent enhancing effects on lentiviral but not NB-MLV infection [21].
 

Physical interactions of TRIM5

  • Disruption of Cyp A binding to CA partially relieved the block to HIV-1 infection imposed by several TRIM5alpha variants, but Cyp A-CA binding was not absolutely required for TRIM5alpha antiviral activity [22].
 

Regulatory relationships of TRIM5

  • We show here that interferon (IFN) upregulates TRIM5alpha mRNA expression in HeLa and HepG2 cells by performing Northern blot analysis and quantitative real-time PCR [23].
