Activity summary

The Discoidin Domain Receptor 2 (DDR2) also known as Tyrosine-protein kinase DDR2 is a receptor tyrosine kinase that binds to collagen initiating various cellular processes. It has a molecular mass of approximately 97 kDa. This receptor is expressed in various tissues including skin bone and cartilage as well as in certain cancer cells. DDR2 activation is achieved through the recognition of specific motifs such as GFOGER in collagen leading to signaling cascades that impact cell functions like adhesion proliferation and extracellular matrix remodeling.

Biological function summary

DDR2 functions as an integral part of the cellular response to collagen. The receptor plays a critical role in the development and maintenance of connective tissues. It exists as a monomer but can form complexes upon ligand binding facilitating its activity. DDR2 signaling influences critical processes such as wound healing and tissue homeostasis by modulating matrix metalloproteinases (MMPs) activity which are important for remodeling the extracellular matrix.

Pathways

DDR2 abettors collagen-induced signal transduction particularly within the mitogen-activated protein kinase (MAPK) pathway and the Src family kinase pathway. These pathways involve proteins like SHP2 and Src both of which interact with DDR2 to propagate cellular signals. DDR2 activation leads to phosphorylation events that stimulate cytoskeletal rearrangements and gene expression modulations relevant to cellular growth and differentiation.

Associated diseases and disorders

DDR2 is linked to fibrosis and cancer. The receptor's overexpression or aberrant signaling can contribute to fibrotic diseases characterized by excessive scarring by promoting collagen deposition and fibroblast proliferation. In cancer DDR2 dysregulation often associates with tumor progression and metastasis particularly in lung cancer and sarcomas. This links DDR2 with other oncogenic proteins and pathways including those governed by MMP proteins which are involved in tumor invasion and metastasis.
