Background:

Gly-Arg-Gly-Asp-Ser is a pentapeptide that forms the cell-binding domain of a glycoprotein, osteopontin.

Gly-Arg-Gly-Asp-Ser binds to integrin receptors αvβ3, with IC50 of 5 μM[1]. GRGDS-immobilized TiO2 nanotubes enhance osteoblast-like cell (MG-63) adhesion, and significantly increased cell spreading and proliferation[2].
