  • Prevalence and significance of the commonest phosphorylated motifs in the human proteome: a global analysis.
    Cell. Mol. Life Sci. (IF 7.014) Pub Date : 2020-02-12
    Luca Cesaro,Lorenzo A Pinna

    Protein phosphorylation is the most frequent post-translational modification by which the properties of eukaryotic proteins can be reversibly modified. In humans, over 500 protein kinases generate a huge phosphoproteome including more than 200,000 individual phosphosites, a figure which is still continuously increasing. The in vivo selectivity of protein kinases is the outcome of a multifaceted and

  • Dynamics of kinetochore structure and its regulations during mitotic progression.
    Cell. Mol. Life Sci. (IF 7.014) Pub Date : 2020-02-12
    Masatoshi Hara,Tatsuo Fukagawa

    Faithful chromosome segregation during mitosis in eukaryotes requires attachment of the kinetochore, a large protein complex assembled on the centromere of each chromosome, to the spindle microtubules. The kinetochore is a structural interface for the microtubule attachment and provides molecular surveillance mechanisms that monitor and ensure the precise microtubule attachment as well, including error

  • Abnormal X chromosome inactivation and tumor development.
    Cell. Mol. Life Sci. (IF 7.014) Pub Date : 2020-02-10
    Dan Wang,Le Tang,Yingfen Wu,Chunmei Fan,Shanshan Zhang,Bo Xiang,Ming Zhou,Xiaoling Li,Yong Li,Guiyuan Li,Wei Xiong,Zhaoyang Zeng,Can Guo

    During embryonic development, one of the two X chromosomes of a mammalian female cell is randomly inactivated by the X chromosome inactivation mechanism, which is mainly dependent on the regulation of the non-coding RNA X-inactive specific transcript at the X chromosome inactivation center. There are three proteins that are essential for X-inactive specific transcript to function properly: scaffold

  • Beta-arrestins operate an on/off control switch for focal adhesion kinase activity.
    Cell. Mol. Life Sci. (IF 7.014) Pub Date : 2020-02-10
    Revu Ann Alexander,Isaure Lot,Kusumika Saha,Guillaume Abadie,Mireille Lambert,Eleonore Decosta,Hiroyuki Kobayashi,Alexandre Beautrait,Aurélie Borrull,Atef Asnacios,Michel Bouvier,Mark G H Scott,Stefano Marullo,Hervé Enslen

    Focal adhesion kinase (FAK) regulates key biological processes downstream of G protein-coupled receptors (GPCRs) in normal and cancer cells, but the modes of kinase activation by these receptors remain unclear. We report that after GPCR stimulation, FAK activation is controlled by a sequence of events depending on the scaffolding proteins β-arrestins and G proteins. Depletion of β-arrestins results

  • Synaptic mitochondrial dysfunction and septin accumulation are linked to complement-mediated synapse loss in an Alzheimer's disease animal model.
    Cell. Mol. Life Sci. (IF 7.014) Pub Date : 2020-02-07

    Synaptic functional disturbances with concomitant synapse loss represent central pathological hallmarks of Alzheimer's disease. Excessive accumulation of cytotoxic amyloid oligomers is widely recognized as a key event that underlies neurodegeneration. Certain complement components are crucial instruments of widespread synapse loss because they can tag synapses with functional impairments leading to

  • A cyclin-dependent kinase, CDK11/p58, represses cap-dependent translation during mitosis.
    Cell. Mol. Life Sci. (IF 7.014) Pub Date : 2020-02-06
    Sihyeon An,Oh Sung Kwon,Jinbae Yu,Sung Key Jang

    During mitosis, translation of most mRNAs is strongly repressed; none of the several explanatory hypotheses suggested can fully explain the molecular basis of this phenomenon. Here we report that cyclin-dependent CDK11/p58-a serine/threonine kinase abundantly expressed during M phase-represses overall translation by phosphorylating a subunit (eIF3F) of the translation factor eIF3 complex that is essential

    As an important chemokine receptor, the role of CX3CR1 has been studied extensively on the migration of lymphocytes including T and B cells. Although CX3CR1+ B cells have immune suppressor properties, little is known about its role on the regulation of BCR signaling and B cell differentiation as well as the underlying molecular mechanism. We have used CX3CR1 KO mice to study the effect of CX3CR1 deficiency

    As predominant pollinators, honeybees are important for crop production and terrestrial ecosystems. Recently, various environmental stresses have led to large declines in honeybee populations in many regions. The ability of honeybees to respond to these stresses is critical for their survival. However, the details of the stress defense mechanisms of honeybees have remained elusive. Here, we found that

    Cell. Mol. Life Sci. (IF 7.014) Pub Date : 2020-02-01
    István Zachar,Gergely Boza

    Endosymbiosis and organellogenesis are virtually unknown among prokaryotes. The single presumed example is the endosymbiogenetic origin of mitochondria, which is hidden behind the event horizon of the last eukaryotic common ancestor. While eukaryotes are monophyletic, it is unlikely that during billions of years, there were no other prokaryote-prokaryote endosymbioses as symbiosis is extremely common

    BACKGROUND Small bowel vascular malformation disease (SBVM) is the most common cause of obscure gastrointestinal bleeding (OGIB). Several studies suggested that EGFL6 was able to promote the growth of tumor endothelial cells by forming tumor vessels. To date, it remains unclear how EGFL6 promotes pathological angiogenesis in SBVM and whether EGFL6 is a target of thalidomide. METHODS We took advantage

    The centromere is a specialized region on the chromosome that directs equal chromosome segregation. Centromeres are usually not defined by DNA sequences alone. How centromere formation and function are determined by epigenetics is still not fully understood. Active centromeres are often marked by the presence of centromeric-specific histone H3 variant, centromere protein A (CENP-A). How CENP-A is assembled
