In biology, a protein filament is a "long chain of proteins, such as those found in hair, muscle, or in flagella". They are often bundled together for strength and rigidity. Some cellular examples include: *Microfilaments (actin filaments) *Microtubules *Intermediate filaments *Myofilaments (composed of myosin or actin) Filaments are also highly dynamic in nature and far from a static structure that acts as a stable "scaffold" for a cell. Some phenomena that profile a protein filaments' dynamics are: *Treadmilling *Nucleation
