  • Keratin ( / ˈ k ɛr ə t ɪ n / ) is one of a family of fibrous structural proteins . (hitchhikersgui.de)
  • By analysis of the primary structures of these keratins and other intermediate filament proteins, Hanukoglu and Fuchs suggested a model that keratins and intermediate filament proteins contain a central ~310 residue domain with four segments in α-helical conformation that are separated by three short linker segments predicted to be in beta-turn conformation.

  • Antisera were prepared to the unfractionated keratin proteins from the follicle and the specificity of these antisera examined by immunodiffusion and immunoelectrophoresis. (biologists.org)
  • form
  • Fibrous keratin molecules supercoil to form a very stable, left-handed superhelical motif to multimerise, forming filaments consisting of multiple copies of the keratin monomer . (hitchhikersgui.de)
