Gene: POSTN (periostin) Homo sapiens
Symbol: POSTN
Name: periostin
Description: Exhibits metal ion binding activity. Involved in cell adhesion and cellular response to vitamin K. Localizes to the collagen-containing extracellular matrix and trans-Golgi network. Biomarker of abdominal aortic aneurysm; chronic kidney disease; congestive heart failure; and degenerative disc disease.
Type: protein-coding
RefSeq Status: REVIEWED
