Receptor tyrosine kinases (RTKs) play a key role in the communication of cells with their microenvironment. These molecules are involved in the regulation of cell growth, differentiation and metabolism. DDR1 is an RTK that is widely expressed in normal and transformed epithelial cells and is activated by various types of collagen. It belongs to a subfamily of tyrosine kinase receptors with a homology region to the Dictyostelium discoideum protein discoidin I in their extracellular domain. Its autophosphorylation is achieved by all collagens so far tested (type I to type VI). In situ studies and Northern-blot analysis show that expression of DDR1 is restricted to epithelial cells, particularly in the kidney, lung, gastrointestinal tract, and brain. In addition, it is significantly over-expressed in several human tumors from breast, ovarian, esophageal, and pediatric brain.
Immunogen
DDR1 (NP_054699, 304-340) This antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide at the Center of human DDR1.
Physical form
Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide.
To investigate the function of discoidin domain receptor 1 (DDR1) in hepatocellular carcinoma (HCC) and to further clarify the underlying mechanism. DDR1 was significantly increased in HCC tissues and cells, which was related to clinical staging and prognosis of HCC.
