Primary and Secondary Structure of IF Protein Chains and Modes of Molecular Aggregationcterized. The first of these classes comprises the keratins, a heterogeneous family of protein chains with molecular weights in the range 40 to 70k; they are expressed in most epithelia. Vimentin chains have a molecular weight of 53k, and are expressed in cells of mesenchymal origin and in cell line
