In biology, a protein filament is a "long chain of proteins, such as those found in hair, muscle, or in flagella".^[1] They are often bundled together for strength and rigidity. Some cellular examples include:

• Microfilaments (actin filaments in the cytoskeleton)
• 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.^{[citation needed]} Some phenomena that profile a protein filaments' dynamics are:^{[citation needed]}

• Treadmilling
• Nucleation
