    Multiple decay events target HAC1 mRNA during splicing to regulate the unfolded protein response

    Patrick D Cherry et al.
    RNA decay is used at multiple points in the budding yeast unfolded protein response to regulate its suppression and activation, and possibly its attenuation.

    SAC1 degrades its lipid substrate PtdIns4P in the endoplasmic reticulum to maintain a steep chemical gradient with donor membranes

    James P Zewe et al.
    SAC1 is unable to adopt an efficient "trans" mode of action in living cells.

    Regulation of cell protrusions by small GTPases during fusion of the neural folds

    Ana Rolo et al.
    The completion of neural tube closure requires small GTPase-regulated membrane protrusions from non-neural ectoderm cells at the tips of the neural folds.

    Behavioral role of PACAP signaling reflects its selective distribution in glutamatergic and GABAergic neuronal subpopulations

    Limei Zhang et al.
    Placing the PACAP/PAC1 signaling within glutamate/GABA cell type and subregional contexts in mouse brain reveals its conspicuous role for sensorimotor circuit interaction through modulating neuronal plasticity.

    Specialization of the chromatin remodeler RSC to mobilize partially-unwrapped nucleosomes

    Alisha Schlichter et al.
    A SWI/SNF-family chromatin remodeling subcomplex from yeast is identified (RSC1) that is specialized to slide nucleosomes residing on DNA sequences that confer partial nucleosome unwrapping, with assistance from accessory factors.

    Mutational sources of trans-regulatory variation affecting gene expression in Saccharomyces cerevisiae

    Fabien Duveau et al.
    Mapping mutations affecting gene expression within the yeast genome and within a gene regulatory network reveals properties of the raw material for regulatory variation.

    A consensus guide to capturing the ability to inhibit actions and impulsive behaviors in the stop-signal task

    Frederick Verbruggen et al.
    Clear guidelines and open-source software resources are provided for the stop-signal task, in order to streamline the use of this important tool, and to thereby increase its validity and reliability.
