Using synthetic peptides and recombinant collagen to understand DDR–collagen interactions

The discoidin domain receptors, DDR1 and DDR2, are a subfamily of receptor tyrosine kinases that are activated upon binding to collagen. DDR-collagen interactions play an important role in cell proliferation and migration. Over the past few decades, synthetic peptides and recombinant collagen have been developed as tools to study the biophysical characteristics of collagen and various protein-collagen interactions. Herein we review how these...
