Intermediate filaments are composed of linear subunits that wrap around each other and interact very tightly. Structurally, as mentioned previously, all intermediate laments start from a fibrous subunit (Figure 12.2. 2 ). This then coils around another filamentous subunit to form a coiled-coil dimer, or protofilament.
