Functions of Microfilaments. In muscle cells, actin filaments are aligned and myosin proteins generate forces on the filaments to support muscle contraction. In non-muscle cells, actin filaments form a track system for cargo transport that is powered by non-conventional myosins such as myosin V and VI. Aug 08,  · Functions of Microfilaments. Microfilaments: Provide structural strength to the cell. Supply resistance to the cell versus the pulling forces. Are accountable for cellular movements like contraction, gliding and cytokinesis (partition of cytoplasm throughout cellular division)/5(57). Calcium levels are low in the leading pseudopod (“False-foot”) and microfilaments assemble and are crosslinked by ABPs, notably filamin. entry across the plasma membrane which in turn triggers gelsolin- mediated microfilament severing.
