In inflammatory arthritis peptidyl arginine deiminase (PAD) enzymes can citrullinate arginine residues in extracellular matrix (ECM) proteins, such as collagens and fibronectin. This may lead to the generation of anti-citrullinated protein antibodies, important diagnostic markers in rheumatoid arthritis. In addition, the citrullination may directly affect protein function. Based on structural analysis, we found that most ECM-associated growth factors (GFs) have arginine residues in their recepto  ...[more]
