    The transcriptional cofactor TRIM33 prevents apoptosis in B lymphoblastic leukemia by deactivating a single enhancer

    Eric Wang et al.
    TRIM33 performs an essential function in B cell acute lymphoblastic leukemia through an association with a single cis element.

    Mechanism of B-box 2 domain-mediated higher-order assembly of the retroviral restriction factor TRIM5α

    Jonathan M Wagner et al.
    Higher-order assembly enables and links pathogen recognition and downstream steps in the TRIM5-mediated anti-HIV response.

    Epithelial magnesium transport by TRPM6 is essential for prenatal development and adult survival

    Vladimir Chubanov et al.
    Mice deficient in the TRPM6 channel suffer from impaired prenatal development, shortened lifespan, growth deficit and disturbed energy balance due to a defect in epithelial Mg2+ uptake, thus highlighting a pivotal role of TRPM6 in organismal Mg2+ homeostasis.

    The E3 ubiquitin ligase TRIM23 regulates adipocyte differentiation via stabilization of the adipogenic activator PPARγ

    Masashi Watanabe et al.
    TRIM23 plays a critical role in the switching from early to late adipogenic enhanceosomes by stabilizing the PPARγ protein.

    Anti-nociceptive action of peripheral mu-opioid receptors by G-beta-gamma protein-mediated inhibition of TRPM3 channels

    Sandeep Dembla et al.
    Pro-nociceptive and pro-inflammatory TRPM3 (transient receptor potential melastatin 3) channels, expressed in somatosensory neurons, are inhibited by activation of Gαi-coupled receptors, such as µ-opioid receptors, in vitro and in vivo.

    Mutational resilience of antiviral restriction favors primate TRIM5α in host-virus evolutionary arms races

    Jeannette L Tenthorey et al.
    Mutations in the TRIM5α retrovirus-binding interface frequently improve but rarely disrupt retroviral restriction.

    Primate TRIM5 proteins form hexagonal nets on HIV-1 capsids

    Yen-Li Li et al.
    To protect mammals against retroviral infections, TRIM5 restriction factors recognize viral capsids by forming complementary hexagonal nets that can adapt to the patterns of capsid protein subunits on the viral capsid surface.

    Disease-associated mutations in the human TRPM3 render the channel overactive via two distinct mechanisms

    Siyuan Zhao et al.
    Disease-associated mutants of the TRPM3 ion channel are overactive, and they are inhibited by the antiepileptic medication primidone, offering a potential therapeutic intervention to treat this channelopathy.

    TRIM28 promotes HIV-1 latency by SUMOylating CDK9 and inhibiting P-TEFb

    Xiancai Ma et al.
    TRIM28 was found to be a versatile dual-function latency contributor by bridging both suppressive epigenetic modifications and RNAP II transcriptional-pausing, and can be a novel target to develop latency-reversing agents.

    Repressing Ago2 mRNA translation by Trim71 maintains pluripotency through inhibiting let-7 microRNAs

    Qiuying Liu et al.
    Repressing the conserved pro-differentiation let-7 microRNAs through limiting Ago2 levels is critical to maintaining pluripotency in stem cells.
