DDR1, also known as epithelial discoidin domain-containing receptor 1 isoform 2, is a transmembrane glycoprotein that belongs to the discoidin-like domain containing subfamily of receptor tyrosine kinases. Expression of this protein is restricted to epithelial cells, particularly in the kidney, lung, gastrointestinal tract, and brain. In addition, it has been shown to be significantly overexpressed in several human tumors. DDR1 oligomerization enhances collagen binding and also modulates collagen fibrillogenesis.
