comparison of the endo b sequence to other intermediate filament proteins reveals 22 residues which are identical in all intermediate filament proteins regardless of whether filament formation requires only one type of protein subunit ( vimentin , desmin , glial fibrillar acidic protein , or a neurofilament protein ) or two dissimilar types ( type i and type ii keratins ) .
