Live cell measurements of interaction forces and binding kinetics between Discoidin Domain Receptor 1 (DDR1) and collagen I with atomic force microscopy

摘要

Background: Discoidin Domain Receptors (DDRs) are membrane-tethered proteins of the receptor tyrosine kinase family, which signal in response to collagen. DDR expression is associated with human diseases, including fibrosis and cancer. The role of DDRs in human pathogenesis is mediated by dysregulated receptor function in response to the collagenous milieu. Thus, understanding DDR-collagen interactions is important for developing novel therapeutic strategies against DDRs.
