| Research Abstract |
Previously, Eta-1 was shown to contain RGD tripeptide sequence that can interact with cell surface receptor, alpha_vbeta_3 integrin. In order to determine whether Eta-1 possesses an additional cell binding site within molecule, we generated various forms of recombinant Eta-1. We then tested the binding of B16-BL6, B16-F10 and L929 cells to various Eta-1. We found that non-RGD domains of Eta-1 promote cell adhesion without involving alpha_v integrin. New cell binding sites were located in both N-terminal and C-terminal halves of Eta-1 molecule. We also found taht receptors for new cell binding sites were expressed by only B16-BL6 cells, but not by B16-F10 and L929 cells.
