The RNA-binding protein, Zfp36, which is critical for resolving inflammation, inhibits the production of proinflammatory cytokines via modulation of the cytoplasmic poly(A)-binding protein.
X-ray crystallography reveals that the Dna2 nuclease-helicase contains a long tunnel through which single-stranded DNA threads, and an allosteric mechanism for displacing the DNA-binding protein Rpa that restricts cleavage to the proper polarity.
The tetrameric structure of a casposase bound to DNA and its biochemical properties show how a transposase could have evolved to perform CRISPR-Cas spacer acquisition.
The structure and composition of the elusive vertex complex in Tectiviridae is finally revealed and the newly reported protein conformations help to maintain the capsid architecture.
The CDC25 family protein phosphatase Mih1 promotes downregulation of cell surface proteins in budding yeast by dephosphorylating a subunit of the retromer complex, which mediates plasma membrane recycling.
The 24-nucleotide long siRNAs that guide cytosine methylation in Arabidopsis are made by dicing short double-stranded RNAs that are only around 30 nucleotides long.
Electron cryo-microscopy has been used to determine the structure of Chikungunya virus-like particles and to provide new insights into their interactions with four different antibodies.
