osteopontin also known as bone sialoprotein (bsp). osteopontin role as a linking protein. it is an extracellular structural protein and therefore an organic component of bone. osteoprontin (opn) binds to several integrin receptors containing α4β1, α9β1, and α9β4 expressed by leukocytes. these receptors have been well-stable to function in cell adhesion, migration, and survival in these cells. i...
