Selective Chemical Crosslinking Reveals a Cep57-Cep63-Cep152 Centrosomal Complex

Kai Johnsson, Pierre Gönczy, Luc Reymond, Grazvydas Lukinavicius, Keitaro Umezawa

The centrosome functions as the main microtubule-organizing center of animal cells and is crucial for several fundamental cellular processes [1]. Abnormalities in centrosome number and composition correlate with tumor progression [2, 3] and other diseases ...

The SCF-FBXW5 E3-ubiquitin ligase is regulated by PLK4 and targets HsSAS-6 to control centrosome duplication

Pierre Gönczy, Debora Keller

Deregulated centrosome duplication can result in genetic instability and contribute to tumorigenesis(1,2). Here, we show that centrosome duplication is regulated by the activity of an E3-ubiquitin ligase that employs the F-box protein FBXW5 (ref. 3) as its ...

PP2A Phosphatase Acts upon SAS-5 to Ensure Centriole Formation in C. elegans Embryos

Pierre Gönczy, Debora Keller

Centrosome duplication occurs once per cell cycle and ensures that the two resulting centrosomes assemble a bipolar mitotic spindle. Centriole formation is fundamental for centrosome duplication. In Caenorhabditis elegans, the evolutionarily conserved prot ...

Phosphorylation of synucleins by members of the Polo-like kinase family

Hilal Lashuel, Harald Hirling, Abid Oueslati, Martial Mbefo Kamdem, Magdalena Zweckstetter

Phosphorylation of alpha-synuclein (alpha-syn) at Ser-129 is a hallmark of Parkinson disease and related synucleinopathies. However, the identity of the natural kinases and phosphatases responsible for regulating alpha-syn phosphorylation remain unknown. H ...

Overly long centrioles and defective cell division upon excess of the SAS-4-related protein CPAP

Pierre Gönczy, Gregor Kohlmaier

The centrosome is the principal microtubule organizing center (MTOC) of animal cells. Accurate centrosome duplication is fundamental for genome integrity and entails the formation of one procentriole next to each existing centriole, once per cell cycle. Th ...

PLK-1 asymmetry contributes to asynchronous cell division of C. elegans embryos

Pierre Gönczy, Yemima Suryani Budirahardja

Acquisition of lineage-specific cell cycle duration is an important feature of metazoan development. In Caenorhabditis elegans, differences in cell cycle duration are already apparent in two-cell stage embryos, when the larger anterior blastomere AB divide ...

The tumor microenvironment and its contribution to tumor evolution toward metastasis

Cancer cells acquire cell-autonomous capacities to undergo limitless proliferation and survival through the activation of oncogenes and inactivation of tumor suppressor genes. Nevertheless, the formation of a clinically relevant tumor requires support from ...

SAS-6 defines a protein family required for centrosome duplication in C. elegans and in human cells

Pierre Gönczy

The mechanisms that ensure centrosome duplication are poorly understood. In Caenorhabditis elegans, ZYG-1, SAS-4, SAS-5 and SPD-2 are required for centriole formation. However, it is unclear whether these proteins have functional homologues in other organi ...
