TRIM5α is an anti-viral restriction factor that inhibits the lifecycle of retroviruses. TRIM5α binds to and forms a hexameric lattice around the retroviral capsid, thereby initiating its antiviral activities, which include: (1) inhibition of viral infection; (2) inhibition of viral reverse transcription; (3) disassembly of the capsid; and (4), activation of innate signaling pathways. The formation of this assembly also activates the E3 ubiquitin ligase function of TRIM5α. Ubiquitin modification is associated with directing substrates to particular cellular pathways. We and others have shown that TRIM5α cytoplasmic bodies colocalize with proteins involved in the autophagy pathway, and we hypothesized that …
