    Ulk4 promotes Shh signaling by regulating Stk36 ciliary localization and Gli2 phosphorylation

    Mengmeng Zhou, Yuhong Han, Jin Jiang
    Phosphorylation of the pseudokinase Ulk4 by Stk36 promotes primary ciliary tip localization of both proteins to facilitate the phosphorylation and activation of Gli in response to Sonic hedgehog.

    ULK3 regulates cytokinetic abscission by phosphorylating ESCRT-III proteins

    Anna Caballe, Dawn M Wenzel ... Juan Martin-Serrano
    ULK3 is a kinase in the abscission checkpoint that temporarily inactivates ESCRT-III proteins via phosphorylation, which is required to delay cytokinesis in response to defects in mitosis.

    Cyclin A/Cdk1 modulates Plk1 activity in prometaphase to regulate kinetochore-microtubule attachment stability

    Ana Maria G Dumitru, Scott F Rusin ... Duane A Compton
    Quantitative phosphoproteomics defines the substrates for Cyclin A/Cdk1 kinase during early mitosis and follow up studies validate that one identified substrate, MYPT1, influences the stability of k-MT attachments by regulating Plk1.

    The autophagy adaptor NDP52 and the FIP200 coiled-coil allosterically activate ULK1 complex membrane recruitment

    Xiaoshan Shi, Chunmei Chang ... James H Hurley
    Hydrogen-deuterium exchange, electron microscopy, and vesicle reconstitution show how binding of the autophagy adaptor NDP52 to the FIP200 subunit of the ULK1 complex triggers membrane binding in autophagy.

    Elevated FBXO45 promotes liver tumorigenesis through enhancing IGF2BP1 ubiquitination and subsequent PLK1 upregulation

    Xiao-Tong Lin, Hong-Qiang Yu ... Chuan-Ming Xie
    Using IGF2BP1-PLK1 axis as an example, targeting oncogenic signaling represents a direction treatment for HCC patients with high FBXO45 expression.

    Multiplex image-based autophagy RNAi screening identifies SMCR8 as ULK1 kinase activity and gene expression regulator

    Jennifer Jung, Arnab Nayak ... Christian Behrends
    An image-based multiplex autophagosome RNAi screen targeting all Rab GTPases as well as their GAPs and GEFs identifies the Rab GEF SMCR8 as multifaceted autophagy modulator, which regulates kinase activity and gene expression of ULK1.

    Comprehensive analysis of the human ESCRT-III-MIT domain interactome reveals new cofactors for cytokinetic abscission

    Dawn M Wenzel, Douglas R Mackay ... Wesley I Sundquist
    A comprehensive, quantitative, protein-protein interaction screen maps the network of interactions between human MIT domains and ESCRT-III C-terminal tails, and reveals MIT domain-containing protein cofactors for abscission and the 'No Cut' abscission checkpoint.

    Imprinted Dlk1 dosage as a size determinant of the mammalian pituitary gland

    Valeria Scagliotti, Maria Lillina Vignola ... Marika Charalambous
    Pituitary gland size and stem cell number is modulated during early life in the mouse by the imprinted gene Dlk1, which acts in multiple developmental compartments in a dosage-sensitive manner.
