Select the correct description explaining the assembly of intermediate filaments. The process requires ATP binding to an intermediate filament protein- two dimers make a tetramer, then association of 8 tetramers form a filament. The process requires GTP binding to an intermediate filament protein- two dimers make a tetramer, then association of 8 tetramers form a filament. No ATP/GTP binding to an intermediate filament protein required - two dimers make a tetramer, then association of 8 tetramers form a filament. O Formation of a triple-helix, as seen in collagen, would be required for the assembly of intermediate filaments.
