Robust designation of meiotic crossover sites by CDK-2 through phosphorylation of the MutS gamma complex

Alexander Woglar

Crossover formation is essential for proper segregation of homologous chromosomes during meiosis. Here, we show that Caenorhabditis elegans cyclin-dependent kinase 2 (CDK-2) partners with cyclin-like protein COSA-1 to promote crossover formation by promoti ...

Identification of novel PCTAIRE-1/CDK16 substrates using a chemical genetic screen

Caterina Collodet

PCTAIRE-1 (also known as cyclin-dependent protein kinase (CDK) 16), is a Ser/Thr kinase that has been implicated in many cellular processes, including cell cycle, spermatogenesis, neurite outgrowth, and vesicle trafficking. Most recently, it has been propo ...

Premature activation of Cdk1 leads to mitotic events in S phase and embryonic lethality

João Pedro de Matos Rodrigues, Patricia Renck Nunes

Cell cycle regulation, especially faithful DNA replication and mitosis, are crucial to maintain genome stability. Cyclin-dependent kinase (CDK)/cyclin complexes drive most processes in cellular proliferation. In response to DNA damage, cell cycle surveilla ...

Physiological regulation of the CDK16/PCTAIRE-1 protein kinase and its proposed role in the brain

Saifeldin Nasser Mohamed Ibrahim Shehata

Cell signalling, mediated to a large extent by protein kinase phosphorylation, plays a vital role in regulation of cellular function. PCTAIRE-1 (also known as cyclin-dependent protein kinase (CDK)16), is a Ser/Thr kinase that has been implicated in many ce ...

Cdk2 strengthens the intra-S checkpoint and counteracts cell cycle exit induced by DNA damage

Gérald Joseph Paul Lossaint

Although cyclin-dependent kinase 2 (Cdk2) controls the G1/S transition and promotes DNA replication, it is dispensable for cell cycle progression due to redundancy with Cdk1. Yet Cdk2 also has non-redundant functions that can be revealed in certain genetic ...

Dynein Transmits Polarized Actomyosin Cortical Flows to Promote Centrosome Separation

Pierre Gönczy, Alessandro De Simone

The two centrosomes present at the onset of mitosis must separate in a timely and accurate fashion to ensure proper bipolar spindle assembly. The minus-end-directed motor dynein plays a pivotal role in centrosome separation, but the underlying mechanisms r ...

Mechanisms of centrosome separation in C. elegans

Alessandro De Simone

Centrosomes are the major microtubule organizing centers of animal cells. The two centrosomes present at the onset of mitosis must separate in a timely fashion along the nuclear envelope to ensure proper bipolar spindle assembly and thus genome stability. ...

The novel Parkinson's disease linked mutation G51D attenuates in vitro aggregation and membrane binding of alpha-synuclein, and enhances its secretion and nuclear localization in cells

Hilal Lashuel, Nadine Aït Bouziad, Martial Mbefo Kamdem, Mohamed Bilal Fares, Ana Jovicic

A novel mutation in the alpha-Synuclein (alpha-Syn) gene "G51D" was recently identified in two familial cases exhibiting features of Parkinson's disease (PD) and multiple system atrophy (MSA). In this study, we explored the impact of this novel mutation on ...

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 ...

Targeting cap-dependent translation blocks converging survival signals by AKT and PIM kinases in lymphoma

Elisa Oricchio

New anticancer drugs that target oncogenic signaling molecules have greatly improved the treatment of certain cancers. However, resistance to targeted therapeutics is a major clinical problem and the redundancy of oncogenic signaling pathways provides back ...

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 ...

Two distinct mechanisms underlie progesterone-induced proliferation in the mammary gland

Cathrin Brisken, Ayyakkannu Ayyanan, Marian Caikovski

The mouse mammary gland develops postnatally under the control of female reproductive hormones. Estrogens and progesterone trigger morphogenesis by poorly understood mechanisms acting on a subset of mammary epithelial cells (MECs) that express their cognat ...

Cyclin D1 Enhances the Response to Estrogen and Progesterone by Regulating Progesterone Receptor Expression

Cathrin Brisken

Estrogen and progesterone are the defining hormones of normal female development, and both play critical roles in breast carcinogenesis. Cyclin D1 is a breast cancer oncogene whose amplification is linked to poor prognosis in estrogen and progesterone rece ...

Decreased Lin7b expression in layer 5 pyramidal neurons may contribute to impaired corticostriatal connectivity in huntington disease

Motor dysfunction, cognitive impairment, and regional cortical atrophy indicate cerebral cortical involvement in Huntington disease (HD). To address the hypothesis that abnormal corticostriatal connectivity arises from polyglutamine-related alterations in ...

Coupling the cell cycle to development

Pierre Gönczy

The core machinery that drives the eukaryotic cell cycle has been thoroughly investigated over the course of the past three decades. It is only more recently, however, that light has been shed on the mechanisms by which elements of this core machinery are ...

Functional characterization of the SAS-4-related protein CPAP in centrosome biology of human cells

The centrosome is an organelle that resides at the center of most animal cells and comprises two microtubule-based centriole cylinders surrounded by pericentriolar material (PCM). The centrosome plays a fundamental role for nucleating and organizing a radi ...

Regulated HsSAS-6 levels ensure formation of a single procentriole per centriole during the centrosome duplication cycle

Pierre Gönczy, Petr Strnad

Centrosome duplication involves the formation of a single procentriole next to each centriole, once per cell cycle. The mechanisms governing procentriole formation and those restricting its occurrence to one event per centriole are poorly understood. Here, ...

CA150 expression delays striatal cell death in overexpression and knock-in conditions for mutant huntingtin neurotoxicity

Patrick Aebischer, Nicole Déglon, Diana Zala

Transcriptional dysregulation caused by expanded polyglutamines (polyGlns) in huntingtin (htt) may be central to cell-autonomous mechanisms for neuronal cell death in Huntington's disease (HD) pathogenesis. We hypothesized that these mechanisms may involve ...

The double life of UPF1 in RNA and DNA stability pathways

Joachim Lingner

The DNA and RNA helicase UPF1 is well known for its central role in Nonsense Mediated RNA Decay (NMD), which promotes degradation of mRNAs containing premature stop codons. However, we have recently demonstrated that human UPF1 is also essential for DNA re ...
