Research Abstract

Dermatopontin (DP), one of the dermal extracellular matrix protein, interacted with fibronectin(Fn), promoted Fn fibril formation, and enhanced cell adhesion. DP enhanced intermolecular interactions of Fn which is important for Fn fibril formation, and DP disrupted interdomain interaction within a Fn molecule which is crucial for maintaining a compact molecular conformation of native Fn. These results indicate that DP changes Fn conformation and renders Fn form fibrils. Moreover, we newly found that DP enhanced the interaction between Fn and VEGF. These results suggest that a complex of DP, Fn, and some cell growth factors could be used as a novel device for positively regulating the wound healing.
