1. Profilin:actin in cell motility : A search for profilin:actin binding proteins
Sammanfattning : The profilin:actin complex is a major source of actin for actin filament growth in vivo. A number of proteins regulating either profilin or actin has been described since profilin:actin was isolated during the 1970s. Since then, profilin and actin and their binding partners have been intensively studied. LÄS MER
2. Cross-linked Profilin:actin - A tool to study actin dynamics in non-muscle cells
Sammanfattning : The microfilament system, consisting of actin and a number of auxiliary proteins, is fundamental for cell motility. Its dynamic organization depends on receptor-mediated signals, leading to rapid polymerizations and depolymerizations of actin. LÄS MER
3. Cell Behavior and the Role of Profilin
Sammanfattning : Profilin is a key regulator of the microfilament system. It binds to actin monomers in a 1:1 complex, forming the profilin:actin complex, which is the major precursor of actin for filament formation in vivo. The distribution of profilin has been studied in a variety of cells. It is present not only in the cytoplasm but also in the nucleus. 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. 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
