Regulation of innate immune signalling pathways by the tripartite motif (TRIM) family proteins.
Bottom Line: The innate immune system recognizes microbial components through pattern-recognition receptors (PRRs), including membrane-bound Toll-like receptors and cytosolic receptors such as RIG-I-like receptors and deoxyribonucleic acid (DNA) sensors.The tripartite motif (TRIM) family is a diverse family of RING finger domain-containing proteins, which are involved in a variety of cellular functions.Importantly, recent studies have shown that they are also involved in the regulation of innate immune responses through the modulation of PRR signalling pathways.

Mentions: The signalling through TLRs, RLRs, DNA sensors and several NLRs culminates in the activation of the nuclear factor κB (NF-κB) and IFN regulatory factor (IRF) families of transcription factors via distinct signalling pathways (Kawai & Akira, 2009). Recent studies have shown that the activations of these pathways are regulated by multiple molecules, including the tripartite motif (TRIM) family, which is one of the largest families of RING domain-containing E3 ligases that mediate post-translational modifications such as protein ubiquitination (Fig 1).
