The Role Of Actin Binding Proteins In Cell Motility, Elizabeth Ojukwu
The Role Of Actin Binding Proteins In Cell Motility, Elizabeth Ojukwu
Honors Scholar Theses
Actin binding proteins (ABPs) play key roles in the dynamic organization of the actin cytoskeleton during cell movement. The general localization of ABPs during dynamic cellular processes has been characterized. However, their specific functions and mechanisms of regulating the cytoskeleton during motile cellular processes remain unclear. Two approaches have been utilized to ask how these proteins contribute to cytoskeletal function during motility. Using homologous recombination, mutant cell lines lacking α-actinin, fimbrin or both proteins have been created. By analyzing mutants that lack these proteins, we hope to disrupt processes that require a functional cytoskeleton such as phagocytosis, random motility, development, …
