IFFO: Proteins and Enzymes

IFFO is a member of the intermediate filament family. Intermediate filaments are proteins which are primordial components of the cytoskeleton and nuclear envelope. The proteins encoded by the members of this gene family are evolutionarily and structurally related but have limited sequence homology, with the exception of the central rod domain. Alternative splicing has been observed for this gene and three transcript variants encoding different isoforms have been identified. Other alternatively spliced transcripts may exist, but their biological validity has not been confirmed. [provided by RefSeq]
