Cyclic di-AMP homeostasis and osmoregulation in Listeria monocytogenes
(2019-04-05)The second messenger cyclic diadenosine monophosphate (c-di-AMP) is essential for most of the bacteria synthesizing the nucleotide. c-di-AMP is produced by diadenylate cyclases (DACs) and degraded by specific phosphodiesterases ... -
Analysis of translational fidelity in cellular proteins
(2019-03-27)The accuracy of protein biosynthesis determines the quality of the proteome and regulates the fitness of the cell. A comprehensive quantification of miscoding events in the cell is essential to understand the basic mechanisms ... -
High-resolution structure determination of human spliceosome complexes by cryo-EM
(2019-02-14)The eukaryotic splicing of precursors to mRNA is facilitated by a highly dynamic, multi-megadalton macromolecular machine termed the spliceosome. The underlying chemical reaction features the excision of an intron, which ... -
Recognition Elements for Elongation Factor P on the Ribosome
(2019-01-25)Translation elongation is a multi-step process orchestrated by elongation factors. Elongation factors G and Tu are required for each round of translation elongation, whereas elongation factor P is only required to assist ... -
A novel function of DPP9 in DNA damage repair via BRCA2 regulation
(2019-01-25)Eukaryotic cells are constantly exposed to exogenous and endogenous agents that induce mutational stresses in their genome, which can lead to genetic lesions, such as chromosome loss, translocations or deletions. The ... -
Identification of a unique oligodendrocyte subpopulation in mouse brain
(2018-10-10)Oligodendrocytes in the central nervous system (CNS) ensheath axons with myelin and are originated from migratory and proliferative progenitor cells, so-called oligodendrocytes progenitor cells (OPCs). While immunoreactivity ... -
Novel export and import pathways in S. cerevisiae identified by an engineered SUMO system
(2018-09-07)Nuclear transport receptors (NTRs) mediate the translocation of cargos between the cytoplasm and the nucleus. NTRs are classified either as importins or exportins according to the directionality of the cargo transport. To ... -
Functional characterization of C/D snoRNA-derived microRNAs
(2018-06-26)miRNAs are essential regulators of cell fate and involved in several human diseases, although their biogenesis is a well-accepted paradigm (microprocessor, Exp5, Dicer, and Argonaute). New evidence revealed different ... -
Molecular insights into the Tau-actin interaction
(2018-05-04)Tau protein is classically considered as a neuronal microtubule-associated protein that stabilizes microtubules and supports the outgrowth of axons. The protein can modulate the transport of vesicles and organelles along ... -
Development of a ‘tool box’ for generating designer nucleosomes in high throughput fashion
(2017-11-23)Post-translational modifications of histones within nucleosomes regulate cell development, cell maintenance and cellular response to external factors. According to the histone code hypothesis, each biologic reaction is ... -
Biochemical characterization of presynaptic membrane protein complexes
(2017-09-13)At chemical synapses, synaptic vesicles, membrane-enclosed entities filled with neurotransmitters, undergo exocytosis at restricted areas of the presynaptic membrane called active zones (AZ). The core AZ proteins form a ... -
Systematic analysis of heterochromatin modification readout
(2017-06-14)Modifications of the building units of chromatin - the histone proteins and DNA - direct the functional readout of the genome and are part of the so called “epigenome” (Fischle et al., 2003b; Kouzarides, 2007). Several ... -
Quantitative phosphoproteomics for studying B-cell receptor signaling in Burkitt’s lymphoma
(2017-02-16)Protein phosphorylation plays an important role in transmitting cellular signals. Phosphorylation has been mostly characterized by hypothesis-driven and low-throughput approaches in the past. However, novel phosphorylation ... -
Structural and functional investigation of cargo recognition by exportins
(2016-11-02)Nucleocytoplasmic exchange is essential for eukaryotic cells. It proceeds through nuclear pore complexes and is largely mediated by Importin β-like nuclear transport receptors (Impβ-like NTRs). According to the direction ... -
Structural Survey on Cohesin and Viomycin Inhibited 70S Ribosome by Single Particle Electron Microscopy
(2016-04-21)Life can be understood as the systematic collaborative action of several entities on molecular level reducing locally the entropy at the cost of the exterior environment. These entities are in great part macromolecular ... -
A Method for the Quantitative Analysis of Protein-Protein Interactions In Vivo
(2016-04-13)The function and activity of proteins is often modulated by other proteins they interact with. To understand cellular behaviour at the system level, a complete description of interactions among different proteins and the ... -
NMR Spectroscopy of the Tau-Microtubule Interaction
(2015-12-10)Tau is an intrinsically disordered, microtubule associated protein and is responsible for the promotion of microtubule (MT) formation and stabilization. The human Tau protein has six different isoforms, which are expressed ... -
Requirements for pre-catalytic B complex formation during exon- and intron-defined spliceosome assembly
(2015-10-07)In eukaryotes, most protein-coding genes are interrupted by non-coding sequences known as introns. The splicing of intronic sequences from a pre-mRNA is catalyzed by the spliceosome, an elaborate molecular machine formed ... -
MS-based quantitative analysis of the CRM1 export pathway and spatial proteomics of the Xenopus laevis oocyte
(2015-09-22)Nuclear export is a vital cellular process, which supplies the cytoplasm with essential biological macromolecules, such as matured tRNAs and ribosomal subunits. This process is carried out by a set of proteins called ... -
Localisation and function of Slam in the early Drosophila embryo
(2014-11-06)Embryogenesis of many insects starts with a syncytial stage characterised by 13 rapid nuclear divisions. During the following interphase, the plasma membrane of the embryo invaginates between each nucleus to give rise to ...
