Structural and Mechanistic Interrogation of Fatty Acid Biosynthesis Machinery
(2025-05-22)Lipids are important molecules for vital functions in the cell, such as energy storage, membrane structure, cellular signaling, and metabolic control. Lipid metabolism is thus one of the central pathways of all living ... -
Characterization of TMEM209, a transmembrane protein of the nuclear envelope
(2025-04-29)The nuclear envelope (NE) comprises the outer nuclear membrane (ONM) and inner nuclear membrane (INM), which are connected at the level of nuclear pore complexes (NPCs). A variety of transmembrane proteins is found at the ... -
Dynamics and composition of signaling droplets reveal an impact of cellular transport during B cell activation
(2025-03-13)B cell activation during immune responses relies on the signaling network downstream the B cell antigen receptor (BCR). BCRs engaged by an antigen recruit a plethora of signal transducers forming BCR signalosomes, which ... -
Investigation of the dual role of mL62 during the mitoribosome assembly and rescue
(2024-12-19)Mitochondria are eukaryotic organelles, which have their own DNA (mtDNA) that encode for 13 proteins that are essential for the oxidative phosphorylation. The mitochondrial ribosome (mitoribosome) is responsible for the ... -
Development of mass spectrometry-based proteome analysis workflows for the systematic study of cardiac disease research models
(2024-09-26)A specific variant of genetic mutation in the phospholamban gene expresses a cardiac phospholamban protein lacking the arginine amino acid at position 14 (R14Δ-PLN). The mutation is believed to have a founder in the ... -
Characterization of Novel Proteins Modulating the Nanoscale Organization of the Membrane-Associated Periodic Skeleton in Neurons
(2024-09-19)The Membrane-associated Periodic Skeleton (MPS) is a lattice located underneath the neuronal plasma membrane, characterized by a distinctive ~190 nm periodic architecture imposed by the nanoscale arrangement of its main ... -
Characterization of Ca2+-triggered (de)ubiquitination events in depolarized synaptosomes by mass spectrometry
(2024-08-15)Communication between neurons takes place at synapses, where the transmission of information from the presynaptic neuron to the postsynaptic cell involves the Ca2+-regulated fusion of synaptic vesicles (SVs) with the ... -
Characterization of abundant unknown proteins that participate in the control of tRNA maturation and fatty acid acquisition in Bacillus subtilis
(2024-07-23)Despite tremendous advances in sequencing and other state-of-the-art technologies, unknown proteins are present in virtually all living organisms. Even though Bacillus subtilis is one of the most extensively annotated model ... -
Investigations of Synaptic Alterations in Models of Parkinson’s Disease
(2024-07-02)Alpha-synuclein (aSyn) is a presynaptic protein implicated in physiological synaptic roles, though its precise function is largely unknown. In Parkinson's disease (PD), the initial pathological events often involve synaptic ... -
Mechanism of non-canonical ubiquitination by ubiquitin conjugating enzyme Ubc6
(2023-10-18)Protein quality control by ubiquitination occurs due to the sequential action of three enzyme classes: ubiquitin-activating (E1), ubiquitin-conjugating (E2) and ubiquitin-ligases (E3). Conventionally, ubiquitin (Ub) ... -
Analysis of multifunctional RNA helicase regulation by protein cofactors in different gene expression processes
(2023-09-11)The biogenesis of ribonucleoprotein (RNP) complexes is a fundamental process in the gene expression network. Assembly of eukaryotic ribosomes and spliceosomes is highly orchestrated and entails the formation of numerous ... -
The role of TRIP13 in DNA damage repair
(2023-08-10)Double-strand breaks, the most toxic DNA lesions, can be repaired via homologous recombination or non-homologous end joining (NHEJ). Using the right pathway at the right time is crucial to maintain genome integrity. ... -
Coordination of the cell cycle and the cytoskeleton during oocyte meiosis
(2023-06-29)Meiosis serves to reduce ploidy, to half the genetic content of germ cells before they unite again at fertilization. This is achieved by two subsequent divisions called meiosis I and II without an intermittent S-phase. In ... -
Actin promotes chromosome aggregation and accurate chromosome segregation in mammalian oocytes
(2022-09-15)Accurate chromosome segregation during meiosis is essential for the formation of a new life. During meiosis, spindle microtubules bind to the chromosomes’ kinetochores and arms in order to separate the genetic material. ... -
Regulation of vesicular trafficking in presence of mutations in contractile proteins
(2022-06-20)The molecular and cellular mechanisms underlying disease phenotypes in dilated cardiomyopathy (DCM) are diverse and to date incompletely understood. Inherited mutations in genes encoding structural components of the sarcomere ... -
The role of proteasome generated spliced peptides in the adaptive immune response
(2022-05-20)CD8+ T-cells are the crucial component of the adaptive immune system as they survey the cells of the body for the signs of pathogens or tumours and eliminate them when necessary. To do this, T-cells recognise short antigenic ... -
Protein Interactions in minimal cells
(2022-05-18)Minimal cells are used to model and understand life’s complex processes. The most essential processes of life are thought to include cell replication, energy metabolism and genome maintenance. However, construction of a ... -
The role of GTPases in human mitochondrial ribosome biogenesis
(2022-05-03)Mitochondria are essential organelles of eukaryotic cells, which produce the vast majority of the cellular ATP via oxidative phosphorylation (OXPHOS). The mitochondrial gene expression machinery contributes to the formation ... -
