    Novel ATP-cone-driven allosteric regulation of ribonucleotide reductase via the radical-generating subunit

    Inna Rozman Grinberg et al.
    Structural and functional characterization of an unanticipated mode of allosteric activity regulation in ribonucleotide reductases controlled by an ATP-cone in the radical-generating subunit.

    Controlling gain one photon at a time

    Gregory W Schwartz, Fred Rieke
    Single absorbed photons trigger adaptational mechanisms that help the retina maintain sensitivity across a wide range of background illumination.

    Analysis of protein phosphorylation in nerve terminal reveals extensive changes in active zone proteins upon exocytosis

    Mahdokht Kohansal-Nodehi et al.
    Global phosphoproteomic analysis in nerve terminal during exocytosis reveals 252 uniquely regulated phosphosites, highlighting complex regulation of active zone proteins at multiple sites and the role of specific kinases/phosphatases.

    Position of UNC-13 in the active zone regulates synaptic vesicle release probability and release kinetics

    Keming Zhou et al.
    The precise position of UNC-13 at the active zone near a synapse depends on the N-terminus of the protein, and the C2A domain in particular, and is essential for accelerating neurotransmitter release.

    Signal transducer and activator of transcription 5 (STAT5) paralog dose governs T cell effector and regulatory functions

    Alejandro Villarino et al.
    Asymmetrical expression dictates functional dominance of one STAT5 paralog at cellular and tissue levels despite redundancy at molecular and genomic levels.

    Transient protein-protein interactions perturb E. coli metabolome and cause gene dosage toxicity

    Sanchari Bhattacharyya et al.
    Weak yet highly species-specific protein-protein interactions enhance the activity of metabolically related enzymes in bacteria at endogenous conditions, but also mean that overexpression of one partner leads to permanent non-physiological complexes and gene dosage toxicity.

    More effective drugs lead to harder selective sweeps in the evolution of drug resistance in HIV-1

    Alison F Feder et al.
    The transition from bad to good treatments for HIV was accompanied by a shift from soft sweeps of many drug resistance mutations spreading simultaneously to harder sweeps of one drug resistant genotype at a time.
