Although keratins are considered to be intracellular cytoskeleton proteins belonging to the family of intermediate filaments
they contain the cell adhesion motifs LDV (leu-asp-val) and RGD (arg-gly-asp)
enabling
cell attachment
and inturn supporting cell growth and development .
Keratins in the formof coatings, fibres and films have also shown promising
cytocompatibility
