TRIM7. a member of the tripartite motif (TRIM) protein family, is a multifunctional E3 ubiquitin ligase implicated in diverse cellular processes, including innate immunity, antiviral defense, and cellular homeostasis. Structurally, it contains a conserved N-terminal RING domain (mediating ubiquitination activity), B-box motifs, and a coiled-coil region, followed by a C-terminal PRY-SPRY domain that facilitates protein-protein interactions. TRIM7 is evolutionarily conserved and widely expressed in human tissues, with emerging roles in regulating viral pathogenesis. For instance, it has been shown to inhibit enterovirus replication by targeting viral proteases for degradation via ubiquitination, while paradoxically enhancing Zika virus infection through mechanisms involving host membrane remodeling.
Recombinant TRIM7 protein is typically produced in heterologous expression systems (e.g., *E. coli* or mammalian cells) with affinity tags (e.g., His or FLAG) to enable purification and functional studies. Its recombinant form allows researchers to investigate enzymatic activity, substrate specificity, and interactions with viral or host proteins in controlled *in vitro* systems. Recent studies highlight TRIM7's involvement in immune signaling pathways, such as modulating NF-κB activation and interferon responses, though its exact mechanisms remain partially characterized. Dysregulation of TRIM7 has been associated with pathological conditions, including cancer progression and neurodegenerative disorders, making it a potential therapeutic target. The development of recombinant TRIM7 has accelerated structural studies (e.g., crystallography of its PRY-SPRY domain) and high-throughput screening for modulators of its E3 ligase activity. However, challenges persist in understanding its context-dependent roles, as TRIM7 appears to exhibit both antiviral and proviral functions depending on the pathogen and cellular environment. Ongoing research leverages recombinant TRIM7 to map its ubiquitination substrates and decipher its dual role in infection and inflammation.
