Phosphorylation of Rif1 by Plk1

ABSTRACT: Polo-like kinase 1 (Plk1) is an important protein kinase for checkpoint recovery and adaptation in response to DNA damage and replication stress. However, although Plk1 is present in S phase, little is known about its localization and function during unperturbed DNA replication. Here used recombinant XRif1 C-terminal domain and recombinant XPlk1 in an in vitro phosphorylation assay followed by LC/MS/MS to identify which residues are phosphorylated by Plk1 on Rif1 CTD.

Identification of Plk1 interacting proteins by XChIP-MS

Project description:Polo-like kinase 1 (Plk1) is an important protein kinase for checkpoint recovery and adaptation in response to DNA damage and replication stress. However, although Plk1 is present in S phase, little is known about its localization and function during unperturbed DNA replication. Using Xenopus laevis egg extracts, mimicking early embryonic replication, we developed a Plk1 chromatin immunoprecipitation approach followed by a proteomic shotgun analysis (XChIP-MS) to identify Plk1 interactions with chromatin and with specific nuclear proteins. We purified and cross-linked nuclei after pre-RC assembly before the start of DNA replication, or later during DNA replication. The DNA was fractionated by sonication and immunoprecipited using anti Plk1 or control antibodies then proteins were analyzed by nanoLC/MS/MS.

Identify HILPS-interacting proteins and HIF1a phosphorylation sites

Project description:To dissect the molecular mechanisms of HILPS in promoting cell survival under hypoxia, we conducted RNA pull-down assay in combination with mass spectrometry analysis to identify HILPS-interacting proteins. Pull-down of antisense HILPS was used as a negative control. To identify the potential phosphorylation site(s), we conducted the in vitro kinase assay in combination with mass spectrometry analysis using PLK1-T210D, recombinant GST-HIF1a and cold ATP. A kinase assay using PLK1-K82R was included as a control.

Project description:We found that LC3B is phosphorylated in vitro by STK3, STK4, NEK9, and PKCζ. To identify phosphorylation sites following in vitro phosphorylation, GST-LC3B was overexpressed in E. coli, purified using glutathione-Sepharose 4 Fast Flow beads and incubated in kinase assays with recombinant kinases or FLAG-tagged kinases immunopurified from transiently transfected HEK293 cells

Extracellular ATP elicits DORN1-mediated RBOHD phosphorylation to regulate stomatal aperture

Project description:A multibillion dollar pharmaceutical industry targets purinergic signaling pathways in humans. However, in contrast, little is known about purinergic signaling in plants. Extracellular adenosine-5’-triphosphate (eATP) acts as a damage-associated molecular pattern (DAMP) in both animals and plants. The first plant eATP receptor, DORN1, was identified in Arabidopsis, defining a new kinase family (P2K) of purinoceptors. Stomates are leaf pores that control gas exchange and, therefore, impact critical functions such as photosynthesis and drought tolerance. Stomates are also the prefer entry point for leaf pathogens. The addition of ATP led to the rapid closure of Arabidopsis leaf stomates resulting in enhanced resistance to the bacterial pathogen Psuedomonas syringae. The data indicate that this response is mediated by eATP recognition by DORN1 followed by direct phosphorylation of the NADPH oxidase RBOHD, resulting in elevated production of reactive oxygen species and stomatal closure. Mutation of the DORN1 phosphorylation sites on RBOHD eliminated the ability of eATP to induce stomatal closure. To date, in contrast to work in animals, purinergic signaling in plants has been viewed as a curiosity without any direct, mechanistic connection to key plant processes. The data presented clearly demonstrates eATP as an important signal controlling stomatal aperture with important implications for the control of plant photosynthesis, water homeostasis, pathogen resistance and ultimately yield.

The Eyes Absent family members EYA4 and EYA1 promote PLK1 activation and successful mitosis through tyrosine dephosphorylation: PLK1 PRM

Project description:The aim of these experiments was to quantify PLK1 tyrosine phosphosites with respect to EYA4 and EYA1. PRM was performed on immunopurified PLK1. This was part of a larger project to characterize the effects of EYA4 mediated dephosphorylation on PLK1 functions.

PLK1 phosphorylation of Epstein-Barr virus nuclear antigen 2

Project description:The Epstein-Barr virus nuclear antigen 2 (EBNA2) initiates and maintains the proliferation of infected B cells. In search of additional cellular strategies, that control EBNA2 function, we have performed a label-free mass spectrometry-based quantification of cellular proteins in EBNA2 immuno-precipitates and found polo-like kinase 1 (PLK1) to be bound to EBNA2. EBNA2/PLK1 complex formation is strongly enforced by EBNA2 S379 phosphorylation catalyzed by the mitotic CYCLIN B/CDK1 complex.

PLK1 signaling coopereates with estrogen receptor-dependent gene transcription.

Project description:Analysis of MCF7 breast cancer cells treated with estadiol for 6 h in presence or absence of the specific PLK1 inhibitor BI2536. Together with CHIP and global phosphoproteome data, the results demonstrate a key role of PLK1 in the estrogen receptor-mediated gene response. Hormone-deprived MCF7 cells were pretreated with BI2536 or vehicle (DMSO) followed by induction with estradiol (E2) or vehicle (ethanol). RNA of each condition was analysed in triplicate on an Agilent Human genome 4x44k v2 microarray [note: MCF7_DMSO_E2_rep3 sample was a clear technical outlier (poor hybridization), and was therefore excluded from the further analysis/this record].
