TRIM25 (EFP) is a RING-finger-dependent E3 ubiquitin ligase that mediates K63-linked ubiquitination of RIG-I CARDs at Lys172, which is required for RIG-I downstream signaling, MAVS binding, and antiviral interferon production. The C-terminal SPRY domain of TRIM25 interacts with the N-terminal CARDs of RIG-I to deliver the ubiquitin moiety. Gene targeting confirmed TRIM25 is essential for RIG-I ubiquitination and IFN-β production in response to RNA virus infection. |

EFP (TRIM25) is a RING-finger-dependent E3 ubiquitin ligase that targets 14-3-3 sigma for ubiquitin-mediated proteasomal degradation, thereby promoting G2→S cell cycle progression and breast cancer cell proliferation. Loss of EFP in MEFs leads to accumulation of 14-3-3 sigma and reduced cell growth. |

EFP (TRIM25) functions as an ISG15 E3 ligase for 14-3-3 sigma, in addition to its ubiquitin E3 ligase activity. EFP's RING domain is required for ISGylation activity, and EFP expression is interferon-inducible. RNAi knockdown of EFP decreased ISGylation of 14-3-3 sigma in 293T cells and MCF-7 cells upon interferon treatment. |

TRIM25 has a dual role in the p53/Mdm2 circuit: TRIM25 inhibits ubiquitination and proteasomal degradation of both p53 and Mdm2, increasing their abundance. Despite increased p53 levels, TRIM25 inhibits p53 transcriptional activity by interfering with p300-Mdm2 interaction (a critical step for p53 polyubiquitination). TRIM25 knockdown increases p53 acetylation and p53-dependent cell death. In medaka, TRIM25 knockdown-induced apoptosis was rescued by co-knockdown of p53. |

Upon viral infection, TRIM25 is redistributed into cytoplasmic dots associated with stress granules, while RIG-I associates with TRIM25/stress granules and then with mitochondrial MAVS. MAVS competes with TRIM25 for RIG-I binding, suggesting that upon TRIM25-mediated K63-ubiquitination, RIG-I moves from TRIM25 to MAVS at mitochondria. Influenza NS1 inhibits TRIM25 homocomplex formation but not RIG-I/TRIM25 heterocomplex formation. |

TRIM25 deletion does not affect the IFN response to influenza A/B, Sendai virus, or RIG-I agonists in mouse or human cell lines, and does not affect RIG-I ubiquitination endogenously, in contrast to RIPLET deletion which completely abrogates RIG-I-dependent IFN responses. Despite this, TRIM25 loss increases susceptibility to IAV infection in vivo, suggesting an alternative antiviral role. |

TRIM25 is a key suppressor of exogenous (LNP-delivered) mRNA turnover; it is activated by acidic pH (protons released from ruptured endosomes), increasing its RNA affinity and inducing turnover of both linear and circular exogenous mRNAs.

N1-methylpseudouridine modification reduces TRIM25's RNA binding, enabling RNAs to evade suppression. |
