    The landscape of antibody binding affinity in SARS-CoV-2 Omicron BA.1 evolution

    Alief Moulana, Thomas Dupic ... Michael M Desai
    The study of the interactions between 65,356 variants of the SARS-CoV-2 receptor binding domain and a panel of monoclonal antibodies shows that Omicron’s escape is driven by a small number of large effect mutations.

    S6K1 phosphorylates Cdk1 and MSH6 to regulate DNA repair

    Adi Amar-Schwartz, Vered Ben Hur ... Rotem Karni
    Unbiased proteomics and molecular analysis revealed a new role for S6K1 in regulating DNA repair through the orchestrated phosphorylation of CDK1 and MSH6. The findings may explain why RPS6KB1 gene amplification contributed to breast cancer drug resistance.

    A distributed residue network permits conformational binding specificity in a conserved family of actin remodelers

    Theresa Hwang, Sara S Parker ... Amy E Keating
    A peptide from PCARE achieves >100-fold binding specificity for the EVH1 domain of ENAH, a protein important for metastasis, using a conformational shift mechanism unavailable to ENAH's closely related paralogs VASP and EVL.
