Monitoring mitochondrial translation with spatial resolution and high throughput strategies
(2023-05-30)Nearly all mitochondrial proteins are encoded in the nuclear genome, synthesized in the cytosol, and imported into mitochondria. However, mitochondria are semi-autonomous and possess their own genome, the mitochondrial DNA ... -
Investigation of Mitochondrial Ribosome Regulators at the Inner Membrane
(2021-09-24)Mitochondrial biogenesis relies on the proper assembly of proteins from dual genetic origin. Nuclear-encoded proteins are imported into the organelle and incorporated into multiprotein complexes together with proteins ... -
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 ... -
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 ... -
Import of proteins along the presequence pathway
(2017-12-01)The aim of this study was to investigate the mechanism of protein transport by the presequence translocase (TIM23) in the inner mitochondrial membrane. Presequencecontaining proteins are imported through the translocase ... -
Function of the INA complex in assembly of the mitochondrial oxidative phosphorylation system
(2017-07-11)The majority of cellular ATP is produced by the mitochondrial F1Fo-ATP synthase, also called complex V, which consists of nuclear- and mitochondrial-encoded subunits. In order to form a functional enzyme, its proteins ... -
Mitochondrial protein assemblies: Biogenesis of the cytochrome c oxidase and mitophagic signaling complexes
(2016-09-05)Mitochondrial physiology requires a constant balance between biosynthesis and degradation events. This thesis addresses both mitochondrial biogenesis, exemplified by cytochrome c oxidase assembly, and mitochondrial removal ... -
Dynamic changes in cytochrome c oxidase assembly and organization
(2016-08-24)The respiratory chain in the inner membrane of the yeast mitochondrion is organized as a network of individual complexes and large supercomplex structures. These supercomplexes are composed of dimeric complex III and one ... -
Analysis of Mdm38 function in mitochondrial translation
(2015-11-05)The data presented in this thesis demonstrate that binding of Mdm38 to ribosomes has conserved characteristics in yeast and E. coli. To gain further insights into potential binding partners, an in vivo photo cross-linking ... -
Analysis of early steps in Assembly of Cytochrome c Oxidase
(2014-12-18)Cytochrome c oxidase (COX) is the terminal enzyme of the respiratory chain. Due to its multimeric nature, assembly and maturation requires the concerted action of over 20 assembly factors in yeast. COX is composed of both ... -
Import of Presequence-Containing Precursor Proteins into Mitochondria
(2014-07-07)The presequence pathway is utilized by over 70% of all cytosolically translated proteins destined to the mitochondria, emphasizing the significance imparted by presequence import on mitochondria translocation. Presequence ... -
Structural and Functional Analysis of the Mitochondrial Presequence Translocase
(2012-09-14)The yeast, Saccharomyces cerevisiae, mitochondrial proteome consists of approximately 1000 proteins, most of which are synthesized on cytosolic ribosomes and therefore require specialized transport systems to reach their ... -
The identification and characterization of Mio10 and MINOS1 as novel regulators of mitochondrial inner membrane organization
(2012-06-07)Various mitochondrial inner membrane proteins contribute to the structure of cristae membranes and to the overall dynamic morphology of the inner membrane. These proteins include the F1FOATPase dimers, which contribute to ... -
Yeast models to study mutations in SURF1 and MPV17 involved in human mitochondrial disorders
(2011-12-06)Mitochondrial diseases are fatal disorders mainly affecting highly energy dependent tissues such as brain, heart, liver and muscle. These severe disorders can be caused by mutations affecting mitochondrial- or nuclear-encoded ...
