osteopontin iso5 Binds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction. Acts as a cytokine involved in enhancing production of interferon-gamma and interleukin-12 and reducing production of interleukin-10 and is essential in the pathway that leads to type I immunity. Belongs to the osteopontin family. Bone. Found in plasma. 5 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
