    ESCRT-III activation by parallel action of ESCRT-I/II and ESCRT-0/Bro1 during MVB biogenesis

    Shaogeng Tang, Nicholas J Buchkovich ... Scott D Emr
    Building on previous work (Tang et al., 2015), novel ESCRT-III subunit Snf7 auto-activation mutants are used to reveal two parallel ubiquitin-dependent pathways during multivesicular endosome biogenesis.

    Sex steroids regulate skin pigmentation through nonclassical membrane-bound receptors

    Christopher A Natale, Elizabeth K Duperret ... Todd W Ridky
    Two receptors have been identified that can be targeted in melanocytes with selective small molecule agonists to modulate human skin color.

    Tethering of an E3 ligase by PCM1 regulates the abundance of centrosomal KIAA0586/Talpid3 and promotes ciliogenesis

    Lei Wang, Kwanwoo Lee ... Brian D Dynlacht
    Ciliogenesis is regulated by a certain group of centriolar satellite proteins, among which an E3 ligase is tethered by PCM1 to maintain the normal level of pro-ciliogenic protein on centrioles.

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

    Alejandro Villarino, Arian Laurence ... John J O'Shea
    Asymmetrical expression dictates functional dominance of one STAT5 paralog at cellular and tissue levels despite redundancy at molecular and genomic levels.

    A novel synaptic plasticity rule explains homeostasis of neuromuscular transmission

    Gilles Ouanounou, Gérard Baux, Thierry Bal
    Skeletal muscle cells constantly monitor their own activity and that of their partner neuron at synapses, enabling them to provide the neuron with feedback regarding neurotransmitter release.

    Activation of PTHrP-cAMP-CREB1 signaling following p53 loss is essential for osteosarcoma initiation and maintenance

    Mannu K Walia, Patricia MW Ho ... Carl R Walkley
    The loss of p53 in bone cells activates critical signaling pathways; these are also essential in bone cancer.

    Quality control in oocytes by p63 is based on a spring-loaded activation mechanism on the molecular and cellular level

    Daniel Coutandin, Christian Osterburg ... Volker Dötsch
    p63 uses an intricate network of domain-domain interactions to control its function in long-term quality maintenance of resting oocytes.

    Degradation of Gadd45 mRNA by nonsense-mediated decay is essential for viability

    Jonathan O Nelson, Kristin A Moore ... Mark M Metzstein
    Excess expression of the Gadd45 mRNA accounts for lethality when nonsense-mediated decay is lost in Drosophila and mammalian cells, revealing that this pathway is a critical gene regulatory mechanism.

    Hypoxia-induced metabolic stress in retinal pigment epithelial cells is sufficient to induce photoreceptor degeneration

    Toshihide Kurihara, Peter D Westenskow ... Martin Friedlander
    Mouse models in which hypoxia can be genetically triggered in retinal pigmented epithelial cells show that hypoxia-induced metabolic stress alone can lead to photoreceptor atrophy/dysfunction.
