Review: DDR1 is one of the potential targets for tumor immunotherapy, and our company has purchased this product multiple times. I used the CSB-MP006595HU product for ELISA experiments, and the EC50 was measured to be 6.111-7.637 ng/ml. The protein shows good activity, stable properties, low batch-to-batch variation, and excellent repeatability. The subsequent experiments have been progressing smoothly. The product procurement is convenient, and the price is favorable. We will continue to purchase from CUSABIO and maintain long-term cooperation!

Target Background

Tyrosine kinase that functions as cell surface receptor for fibrillar collagen and regulates cell attachment to the extracellular matrix, remodeling of the extracellular matrix, cell migration, differentiation, survival and cell proliferation. Collagen binding triggers a signaling pathway that involves SRC and leads to the activation of MAP kinases. Regulates remodeling of the extracellular matrix by up-regulation of the matrix metalloproteinases MMP2, MMP7 and MMP9, and thereby facilitates cell migration and wound healing. Required for normal blastocyst implantation during pregnancy, for normal mammary gland differentiation and normal lactation. Required for normal ear morphology and normal hearing. Promotes smooth muscle cell migration, and thereby contributes to arterial wound healing. Also plays a role in tumor cell invasion. Phosphorylates PTPN11.
