Predicted to enable cell adhesion molecule binding activity; heparin binding activity; and metal ion binding activity. Involved in several processes, including bone regeneration; cellular response to growth factor stimulus; and negative regulation of cell-substrate adhesion. Located in cytoplasm; extracellular space; and neuromuscular junction. Used to study congestive heart failure. Biomarker of artery disease (multiple); degenerative disc disease; end stage renal disease; periodontitis; and tendinitis. Orthologous to human POSTN (periostin).
