PtdIns(4,5)P2

  • SHORT REPORT
    Phosphatidylinositol 4,5-bisphosphate regulates cilium transition zone maturation in Drosophila melanogaster
    Alind Gupta, Lacramioara Fabian, Julie A. Brill
    Journal of Cell Science 2018 131: jcs218297 doi: 10.1242/jcs.218297 Published 17 August 2018

    Summary: The membrane phospholipid PIP2, and the kinase that produces PIP2, called Skittles, are needed for normal ciliary transition zone morphology and function in the Drosophila male germline.

  • RESEARCH ARTICLE
    Nuclear phosphatidylinositol 4,5-bisphosphate islets contribute to efficient RNA polymerase II-dependent transcription
    Margarita Sobol, Alžběta Krausová, Sukriye Yildirim, Ilona Kalasová, Veronika Fáberová, Vladimír Vrkoslav, Vlada Philimonenko, Pavel Marášek, Lukáš Pastorek, Martin Čapek, Zuzana Lubovská, Lívia Uličná, Takuma Tsuji, Miroslav Lísa, Josef Cvačka, Toyoshi Fujimoto, Pavel Hozak
    Journal of Cell Science 2018 131: jcs211094 doi: 10.1242/jcs.211094 Published 13 April 2018

    Summary: A novel nuclear structure – nuclear lipid islets – might serve as a structural platform for the formation of Pol II transcription factories, thus participating in the formation of transcription-competent architecture.

  • COMMENTARY
    Emerging roles of PtdIns(4,5)P2 – beyond the plasma membrane
    Xiaojun Tan, Narendra Thapa, Suyong Choi, Richard A. Anderson
    Journal of Cell Science 2015 128: 4047-4056; doi: 10.1242/jcs.175208

    Summary: In this Commentary, we review current evidence supporting intracellular PtdIns(4,5)P2 signaling, with a focus on PtdIns(4,5)P2 regulation of endolysosomal trafficking and protein recycling, as well as autophagic membrane trafficking.
