1. Profilin in cell motility and signal transduction studies using site-specific mutagenesis
Sammanfattning : When a cell is stimulated by signalling molecules such as growth factors, one immediate response is an increased motile activity of the cell. Membrane lamella and spikes appear at the cell surface and perform undulating movements. LÄS MER
2. The eukaryotic ribosome in focus : a chemical footprinting analysis of ribosome-ligand interactions in in vivo assembled complexes
Sammanfattning : Protein synthesis is an essential biological process that occurs on ribosomes. The process requires an involvement of numerous components like mRNA, tRNA and translation factors. The mammalian 80S ribosome, the focus of this thesis, is composed of four rRNAs and approximately 80 proteins distributed in two subunits the 40S and 60S subunit. LÄS MER
3. The molecular dynamics of actin : role of nucleotide, divalent cation, and actin binding proteins for the interdomain relationship in actin
Sammanfattning : .... LÄS MER
4. The dynamic microfilament system : cellular organization of actin and profilin and their association with cell signalling
Sammanfattning : Active shape changes and movement of whole cells, and translocations within cells are essential to life. For instance, during embryogenesis cell migration is a central theme. Wound healing depends on increased and directed motile activity of several cell types. LÄS MER
5. Structural and functional studies of the ribosomes : a closer look at expansion segments and translational dynamics in eukaryotes
Sammanfattning : The ribosome is the basic machinery for protein synthesis in all living cells. In the last decade, there has been an explosion of structural information on the ribosome. The eukaryotic ribosome is larger than the prokaryotic counterpart and contains several extra features, even though they have similar core structures. LÄS MER
