rotein domains and peptide sequences are a powerful tool
for conferring specific functions to engineered biomaterials.
Protein sequences with a wide variety of functionalities,
including structure, bioactivity, protein–protein interactions,
and stimuli responsiveness, have been identified, and
advances in molecular biology continue to pinpoint new
sequences. Protein domains can be combined to make
recombinant proteins with multiple functionalities. The high
fidelity of the protein translation machinery results in
exquisite control over the sequence of recombinant proteins
and the resulting properties of protein-based materials. In
this review, we discuss protein domains and peptide
sequences in the context of functional protein-based
materials, composite materials, and their biological
applications
