    Primate TRIM5 proteins form hexagonal nets on HIV-1 capsids

    Yen-Li Li, Viswanathan Chandrasekaran ... Wesley I Sundquist
    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.

    Rare missense variants in the human cytosolic antibody receptor preserve antiviral function

    Jingwei Zeng, Greg Slodkowicz, Leo C James
    Studying the impact of natural variation on a key immune gene highlights how focusing on a single wild-type sequence overlooks that rare variants cause the most disease.

    PITAR, a DNA damage-inducible cancer/testis long noncoding RNA, inactivates p53 by binding and stabilizing TRIM28 mRNA

    Samarjit Jana, Mainak Mondal ... Kumaravel Somasundaram
    PITAR interaction with TRIM28 mRNA, which encodes a p53 targeting E3 ubiquitin ligase, keeps p53 levels low for cancer cells to divide and attenuates the DNA damage response by p53.

    RTN3 inhibits RIG-I-mediated antiviral responses by impairing TRIM25-mediated K63-linked polyubiquitination

    Ziwei Yang, Jun Wang ... Ersheng Kuang
    RTN3 is upregulated upon RNA viral infection, in turn suppresses antiviral responses by impairing TRIM25-mediated RIG-I K63-linked polyubiquitination and decreases neutrophil populations and inflammatory infiltration, representing a novel inflammatory resolution.

    Tim29 is a novel subunit of the human TIM22 translocase and is involved in complex assembly and stability

    Yilin Kang, Michael James Baker ... Diana Stojanovski
    A novel and metazoan-specific protein, Tim29, is identified as a subunit of the human TIM22 complex and shown to function in the assembly of hTim22 and facilitate contacts with the TOM complex.
