Intermediate filaments are the only nonpolar fibrous component of the cytoskeleton and are not associated with motor proteins. Intermediate filaments are built from coiled coil dimers that associate in an antiparallel fashion into tetramers and then into protofilaments, 16 of which make up the filament. There are five major classes of intermediate filament proteins. Match the following proteins (Column I) with their class (Column II).

Column I	Column II
A. Lamins	a. Class I
B. Keratins	b. Class II
C. Desmin	c. Class III
D. Neurofilaments	d. Class IV
	e. Class V
