TRIM family proteins are a diverse group of proteins with a conserved tripartite motif (RBCC) that includes a RING domain, one or two B-box domains, and a coiled-coil domain. These proteins play critical roles in innate immunity, including antiviral and antimicrobial activities, and are involved in pathogen recognition and signaling pathways. TRIM proteins are induced by type I and II interferons, which are crucial for immune responses against pathogens. They are also involved in the restriction of lentivirus infections. TRIM proteins have a variety of functions, including ubiquitylation, sumoylation, and ISGylation, which contribute to their biological flexibility. They can self-associate to form large protein complexes in cytoplasmic or nuclear compartments. TRIM proteins are involved in various biological processes, including genetic disorders, neurological disorders, and cancers. They are present in all metazoans, with more members in humans and mice than in worms and flies. TRIM proteins have distinct domains, including the RING domain, B-box domains, and coiled-coil domains, which are involved in various functions such as ubiquitylation, protein-protein interactions, and subcellular localization. The PRY and SPRY domains are important for viral recognition and immune responses. TRIM proteins are also involved in the regulation of IFN signaling, which is crucial for innate immunity. TRIM proteins are involved in the restriction of retroviral infections, including HIV. They can inhibit different stages of the viral life cycle, such as viral binding, fusion, and budding. TRIM5α is a key restriction factor for HIV, recognizing the viral capsid. TRIM25 is involved in the RIG-I signaling pathway, which is important for antiviral responses. TRIM proteins also regulate TLR signaling, which is crucial for innate immune responses. TRIM proteins are involved in the regulation of cytokine gene transcription and the modulation of signaling pathways triggered by PRRs. They can interact with viral components and modulate signaling pathways that affect the expression of type I and II IFNs and pro-inflammatory cytokines. TRIM proteins are also involved in the regulation of innate immune responses, including the formation of nuclear bodies and the regulation of NF-κB and IRF signaling pathways. Overall, TRIM proteins are essential for innate immunity and have diverse functions in immune responses, including antiviral and antimicrobial activities, pathogen recognition, and signaling pathways. Their roles in immune responses are increasingly understood, and they are important targets for the development of strategies to prevent or combat infectious diseases, inflammatory conditions, and autoimmune disorders.TRIM family proteins are a diverse group of proteins with a conserved tripartite motif (RBCC) that includes a RING domain, one or two B-box domains, and a coiled-coil domain.
