title: Evolutionary aspects in intermediate filament proteins.
abstract: Intermediate filament (IF) proteins, together with tubulins and actins, constitute the majority of cytoskeletal proteins in metazoans. Proteins of the IF family fulfil increasingly diverse functions but share common structural features. Phylogenetic analysis within the metazoan lineage traces back their origin to a common lamin-like ancestor. Major steps in lamin evolution occurred at the base of the vertebrate radiation, while cytoplasmic IF protein subfamilies evolved independently in the major metazoan lineages.
