In this dissertation, a new framework called bead-state model (BSM) for computer simulations of actin networks is presented, and its scientific validity and its usability and flexibility is demonstrated in three proof-of-concept scenarios. G-actin is a globular protein that can polymerize into semi-flexible actin fibers of several micrometer length. These actin fibers are one of the major constituents of the cells cytoskeleton, and as such they play a main role in the cells active motility as well as its response to external mechanical stimuli. Actin networks display a large variety of different network architectures and properties, allowing them to fulfill various different roles. One main driver for these differences is the interplay between actin and the vast family of actin binding proteins. Due to their importance, actin along with actin binding proteins are subject to many in vivo, in vitro and in silico studies. For in silico studies, open source frameworks like ...
