Depletion of respiratory chain complexes modulates cristae architecture via MIC10 in human cells
(2024-10-18)The complex structure of the inner mitochondrial membrane plays a key role in mitochondrial function. The inner mitochondrial membrane is divided into the inner boundary membrane and the cristae membrane, which is characterized ... -
Biochemical reconstitution of human autophagy initiation
(2023-05-04)Autophagy is a tightly regulated process that eukaryotic cells use as a major survival mechanism to reallocate nutrients to essential processes in adverse conditions such as nutrient or energy deprivation. Autophagy is ... -
Modifications in AP2 and clathrin-mediated endocytosis as a mechanism of synaptic plasticity
(2022-07-01)AP2 CME fulfills essential functions in embryonic development and cell survival. The AP2 complex and clathrin form AP2 CCV together with sixty other coat proteins. Due to this complex protein network, the regulation of CCV ... -
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. ... -
The roles of RNA helicases and other ribosome biogenesis factors during small subunit maturation
(2020-05-29)RNA helicases are a highly conserved family of proteins that act as RNA-dependent NTPases. These proteins contain a conserved helicase core consisting of two RecA-like domains that are responsible for unwinding or annealing ... -
Dissection of the molecular machinery of micro- and macronucleophagy
(2019-11-07)A highly conserved pathway required for cellular homeostasis, autophagy facilitates degradation and recycling of various cellular components. Involvement of autophagy in medical context has made associated research a highly ... -
Atg21 restricts Atg8 lipidation to a novel vacuole-phagophore contact site
(2019-07-01)Macroautophagy is a degradative membrane trafficking pathway that removes and recycles cellular components to maintain cellular homeostasis. Targets for degradation are a variety of cytosolic components including protein ... -
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 therapeutic targets in the Burkitt’s lymphoma specific B cell antigen receptor signaling network
(2018-11-12)Burkitt’s lymphoma (BL) is an aggressive B cell neoplasm that is characterized by a chromosomal translocation, which brings the proto-oncogene c-MYC under the control of Immunoglobulin (Ig) enhancer elements leading to ... -
Functional characterisation of RNA helicases in the remodelling of pre-ribosomal subunits
(2018-07-13)DEAD/H-box RNA helicases are ubiquitously expressed enzymes, which are characterised by a conserved helicase core of two RecA-like domains containing sequence motifs required for substrate binding and hydrolysis of NTP. ... -
Role of WRB protein in cardiac function
(2017-08-24)The mammalian TRC40 system is a conserved pathway responsible for the post-translational targeting of tail-anchored proteins, which are characterized by a single transmembrane domain at the C-terminus and an N-terminus ... -
A Role For Microtubule Dynamics For The Induction Of Chromosomal Instability And Cell Migration And Invasion In Human Cancer Cells
(2017-06-21)Aneuploidy and increased cell migration and invasion are hallmarks of aggressive human cancers. Aneuploidy derives from an increased rate of perpetual chromosome missegregation during mitosis, referred to as chromosomal ... -
Structural, biochemical and computational studies on PROPPINs, proteins important in autophagy
(2015-12-16)PROPPINs (β-propellers that bind polyphosphoinositides) are conserved eukaryotic proteins that play an important role in autophagy. Yeast contains three PROPPINs: Atg18, Atg21 and Hsv2 (homologous with swollen vacuole ... -
Atg21 functions during autophagy as a scaffold for the E3 ubiquitin-‐like complex in Atg8 lipidation
(2015-01-23)Autophagy summarizes a family of intracellular lysosomal (vacuolar) degradative transport process. It is used for the removal and recycling of cytoplasm, protein aggregates and organelles to maintain cellular homeostasis. ... -
Studying Protein Organization in Cellular Membranes by High-Resolution Microscopy
(2014-10-09)Most membrane proteins are found in clusters in the plasma membrane. For abundant proteins it is apparent that the clusters also tend to have patterned distributions, rather than being randomly scattered. To reveal the ... -
Crystal Structure and Characterization of the SCOC Coiled Coil Domain
(2014-08-06)Autophagy is a conserved eukaryotic process for the degradation of cytosolic content. An expanding double layered membrane takes up part of the cytoplasm and matures to an autophagosomal vesicle. The autophagosome ... -
Insights into membrane binding of PROPPINs and Reconstitution of mammalian autophagic conjugation systems
(2013-06-24)Autophagy is a degradation pathway conserved in eukaryotes. Upon induction of autophagy a double layered membrane is formed de novo and engulfs the cytosolic content. After fusion of the membrane, an autophagosome vesicle ... -
