Cryo-electron microscopy structures of human ribonucleotide reductase reveal molecular details of substrate selection and allosteric inhibition through assembly of its large subunit into a ring that excludes its small subunit.
Mutation of Glycine 34 to Arginine within the N-terminal tail of histone H3 alters post-translational modifications on Lysine 36 and is associated with a delay in replication restart, defective homologous recombination and an increase in genomic instability.
A comprehensive whole cell proteomic map describing expression time courses of >6,500 viral and cellular proteins during HIV infection identifies Vif-dependent antagonism of key cellular phosphatase PP2A.
A detailed analysis of protein abundance and phosphorylation changes across mitotic subphases and interphase in asynchronously growing human cells has been enabled by combining FACS with quantitative MS-based proteomics.
Morphological and functional rejuvenation upon exit from adult reproductive diapause in C. elegans is independent of germline signaling, but instead involves somatic nucleolar activation and expansion of the RNA pool.
