Several proteins are integral to the process of cytokinesis:
- Actin and Myosin: These are the primary components of the contractile ring in animal cells. Actin filaments provide the structural framework, while myosin motor proteins generate the force required for contraction.
- RhoA: This small GTPase regulates the assembly and contraction of the contractile ring by controlling the organization of actin filaments.
- Septins: These proteins form a scaffold at the site of division, guiding the assembly of the contractile ring and ensuring proper membrane insertion.
- FtsZ: In plant cells, FtsZ proteins play a role in forming the initial scaffold for the cell plate.
