    Activation of Discs large by aPKC aligns the mitotic spindle to the polarity axis during asymmetric cell division

    Ognjen Golub et al.
    The Par complex controls spindle orientation during asymmetric cell division by phosphorylating the tumor suppressor Discs large, overcoming its autoinhibited state, and allowing it to bind the microtubule-binding protein GukHolder.

    Pak1 and PP2A antagonize aPKC function to support cortical tension induced by the Crumbs-Yurt complex

    Cornelia Biehler et al.
    Cell biology analyses in Drosophila epithelial tissues reveal novel mechanisms connecting epithelial polarity proteins with Myosin-dependent cell contractility.

    Munc18-1 is a dynamically regulated PKC target during short-term enhancement of transmitter release

    Özgür Genç et al.
    Protein kinase C brings about post-tetanic potentiation - a temporary increase in synaptic strength due to increased transmitter release - via phosphorylation of a target protein, Munc18-1.

    ARID1A loss in adult hepatocytes activates β-catenin-mediated erythropoietin transcription

    Rozenn Riou et al.
    A chromatin remodeling factor cooperates with Wnt signaling pathway to transcribe erythropoietin in the adult liver, inducing its secretion and a dramatic erythropoiesis in the spleen.

    Regulation of mRNA translation during mitosis

    Marvin E Tanenbaum et al.
    Ribosomal profiling reveals that translational repression is an important mechanism for cell cycle control and can complement protein degradation.

    CD40 is a major regulator of dendrite growth from developing excitatory and inhibitory neurons

    Paulina Carriba, Alun M Davies
    CD40-activated CD40L-mediated reverse signalling has strikingly opposite effects on the growth of excitatory and inhibitory neuron dendrites in the developing brain of mice.

    Genetic analysis reveals functions of atypical polyubiquitin chains

    Fernando Meza Gutierrez et al.
    A comprehensive genetic interaction screen uncovered biological roles of K11 linkages in amino acid homeostasis and cell cycle regulation in yeast.

    Apical PAR complex proteins protect against programmed epithelial assaults to create a continuous and functional intestinal lumen

    Maria Danielle Sallee et al.
    During intestinal development, apical PAR complex proteins keep apical domains and junctions continuous between cells as they divide and elongate, and ultimately build a continuous functional tube.

    FAK/PYK2 promotes the Wnt/β-catenin pathway and intestinal tumorigenesis by phosphorylating GSK3β

    Chenxi Gao et al.
    Dual FAK/PYK2 kinase inhibition disrupts GSK3β phosphorylation and may present a new treatment for colorectal cancer in patients carrying APC mutations.
