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

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

Kei Sakamoto, Maria Deak, 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

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, Katarina Bacevic

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, Mohamed Bilal Fares, Martial Mbefo Kamdem, 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 ...
