Molecular insights into the roles of RNA helicases during large ribosomal subunit assembly
(2021-02-25)RNA helicases are enzymes present in all domains of life that are important in many aspects of RNA metabolism. They harbor a conserved helicase core that uses the energy of NTP binding and hydrolysis to change affinity to ... -
Kinetic Analysis of Mammalian Translation Initiation
(2021-01-22)During translation initiation in mammalian cells, 80S ribosomes are assembled at the translation start site on mRNA via a cap-dependent scanning mechanism. The formation of the 80S initiation complex (IC) is essential for ... -
Signal transduction by the essential nucleotide second messenger cyclic di-AMP in Bacillus subtilis
(2021-01-15)Bacillus subtilis, as a soil inhabitant, has to adapt to rapidly changing osmotic conditions. The response to these osmotic changes represents one of the most critical issues in the lifecyle of bacteria, and the tight ... -
Investigation of early assembly of OXPHOS complexes during mitochondrial translation
(2020-12-02)After a long time of coevolution between mitochondria and their eukaryotic host cells, the mitochondrial genome has diverged severely from it’s α- proteobacterial ancestors. Mitochondrial genes have mainly been transferred to ... -
An omics analysis of genetic sleep loss in C. elegans
(2020-11-24)Sleep is a state of consciousness that has persisted through evolution and has become a necessity for animal welfare. In humans sleep loss has been shown to be inextricably intertwined with poor health. The prevalence ... -
Insights into the biogenesis of the human mitochondrial ribosomal large subunit – Characterisation of mL44 and mL45
(2020-11-16)Due to the presence of high-resolution cryo-EM structures of the human mitoribosome, the understanding about the function and assembly of the intriguing mitochondrial ribonucleoprotein complex increased tremendously during ... -
Investigating phase separation mechanisms for transcriptional control
(2020-11-13)Transcription of protein-coding genes by RNA polymerase (Pol) II is a highly coordinated process. In metazoan cells, transcription is regulated both at the initiation step by recruitment of the Pol II machinery as well as ... -
Reconstitution of Doa10-mediated ER-associated protein degradation with purified components
(2020-11-09)ER-associated protein degradation (ERAD) is a protein quality control pathway at the ER membrane mediated by membrane-embedded ubiquitin ligase complexes. During ERAD, membrane and luminal proteins are ubiquitinated and ... -
Insights into mitochondrial presequence and carrier import pathways
(2020-10-20)The mitochondria of yeast Saccharomyces cerevisiae contains more than 1000 proteins, majority of which are imported from the cytosol. The TIM23 and the TIM22 complexes in the inner mitochondrial membrane are essential ... -
The Mediator kinase module: structural and functional studies in transcription regulation
(2020-10-15)Transcription of protein-coding genes occurs when RNA polymerase II (RNAPII) and general transcription factors (GTFs) assemble at genomic promoter regions, forming a transcription pre-initiation complex (PIC), which ... -
Identification of peptide-RNA heteroconjugates by mass spectrometry
(2020-10-12)Proteins and nucleic acids are two of the major constituents of life and their interplay is at the center of most biological processes. A deep understanding of the interaction between these biomolecules is crucial for ... -
Analysis of the Interactome and Membrane Insertion of VAPB, a Tail- Anchored Protein at the Inner Nuclear Membrane
(2020-06-26)Tail-anchored (TA) proteins are a group of integral membrane proteins defined by the presence of a single transmembrane domain (TMD) at the C-terminal domain and are involved in functionally diverse cellular processes. ... -
Reconstitution of retrotranslocation by the Hrd1 ubiquitin ligase with purified components
(2020-03-11)In eukaryotic organisms, a large fraction of newly-synthesized proteins are destined for the endomembrane system or for secretion. The entry gate for these proteins is the endoplasmic reticulum (ER). Proteins are imported ... -
Structure of mammalian RNA polymerase II elongation complex bound by α-amanitin and study of mammalian transcription termination and 3’ end processing
(2019-12-04)Chapter 1 RNA polymerase II (Pol II) is the central enzyme that transcribes eukaryotic protein-coding genes to produce mRNA. The mushroom toxin α-amanitin binds Pol II and inhibits transcription at the step of RNA chain ... -
Investigating post-translational modifications and novel interaction partners of otoferlin
(2019-10-30)Otoferlin is a large multi-C2-domain protein essential for hearing and fast Ca2+-triggered transmitter release from auditory IHCs. Mutations in the OTOF gene are linked to a form of autosomal recessive non-syndromic hearing ... -
Structure-based mechanistic analysis of the proteasome
(2019-05-02)The ubiquitin proteasome pathway is one of the major protein degradation pathways in the cell. This pathway is essential for protein quality control and the regulation of the cell cycle. Proteins subjected to the ubiquitin ... -
