In this article we will explore in detail DDR1, a topic that has aroused the interest of various sectors and that has generated a wide debate in today's society. DDR1 has significantly impacted various aspects of our daily lives, and its influence has become increasingly evident in recent years. Through a comprehensive analysis, we will examine the many facets of DDR1, from its origins and history to its implications in today's world. Additionally, we will examine how DDR1 has evolved over time and how it has affected different people and communities around the world. This topic is of great relevance today, so it is essential to understand its ramifications and challenges in order to address it effectively.
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. The protein encoded by this gene is a RTK that is widely expressed in normal and transformed epithelial cells and is activated by various types of collagen. This protein 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). A closely related family member is the DDR2 protein.[6] In situ studies and Northern-blot analysis showed that expression of this encoded protein is restricted to epithelial cells, particularly in the kidney, lung, gastrointestinal tract, and brain. In addition, this protein is significantly over-expressed in several human tumors from breast, ovarian, esophageal, and pediatric brain. This gene is located on chromosome 6p21.3 in proximity to several HLA class I genes. Alternative splicing of this gene results in multiple transcript variants.[5]
