    Distinct roles for S. cerevisiae H2A copies in recombination and repeat stability, with a role for H2A.1 threonine 126

    Nealia CM House, Erica J Polleys ... Catherine H Freudenreich
    Despite differing by only one amino acid in the C-terminal tail, copy 1 of yeast histone 2A has a repair-specific role not shared by copy 2.

    The photosystem I supercomplex from a primordial green alga Ostreococcus tauri harbors three light-harvesting complex trimers

    Asako Ishii, Jianyu Shan ... Jun Minagawa
    The structure of the photosystem I (PSI) supercomplex in Ostreococcus tauri has revealed a unique hybrid of both plant-type and green algal-type PSI supercomplexes with three Lhcp trimers located at the ‘state 2’ position.

    Distinct trafficking routes of polarized and non-polarized membrane cargoes in Aspergillus nidulans

    Georgia Maria Sagia, Xenia Georgiou ... Sofia Dimou
    Unconventional secretion of a plasma membrane purine transporter via Golgi-bypass is established at an early ER-associated secretory compartment revealing that specific cargoes define alternative trafficking routes.

    How cells determine the number of polarity sites

    Jian-geng Chiou, Kyle D Moran, Daniel J Lew
    Minimal essential features of Rho GTPase systems are elucidated that regulate the number of distinct domains developed by a cell’s polarity machinery, which in turn governs cell shape.

    Inherent regulatory asymmetry emanating from network architecture in a prevalent autoregulatory motif

    Md Zulfikar Ali, Vinuselvi Parisutham ... Robert C Brewster
    Network architecture and physiological features of the cell dictate asymmetric gene regulation between a negative autoregulatory TF gene and its target gene.

    Optimal cancer evasion in a dynamic immune microenvironment generates diverse post-escape tumor antigenicity profiles

    Jason T George, Herbert Levine
    Theoretical modeling reveals how stochastic optimal cancer immune evasion via antigen downregulation gives rise to diverse post-escape cancer antigenic profiles in a manner dependent on the immune microenvironment.

    Dendritic coincidence detection in Purkinje neurons of awake mice

    Christopher J Roome, Bernd Kuhn
    Simultaneous voltage and calcium two-photon imaging of Purkinje neuron dendrites in awake mice reveals multiple interplaying mechanisms underlying sensory-evoked dendritic coincidence detection of parallel fiber and climbing fiber input.
