Alpha-keratins are mostly fibrous, and their structure looks like the thread of a screw (helical). Fabrication of poly(-caprolactone)/keratin nanofibrous mats as a potential scaffold for vascular tissue engineering. Like all intermediate filaments, keratin proteins form filamentous polymers in a series of assembly steps beginning with dimerization; dimers assemble into tetramers and octamers and eventually, if the current hypothesis holds, into unit-length-filaments (ULF) capable of annealing end-to-end into long filaments.
