RESUMEN
A novel protein for controlling cellular functions was constructed by combining functional units of various proteins. The Arg-Gly-Asp (RGD) sequence functioning as a cell adhesive function, an epidermal growth factor (EGF) as a cell growth function, and a hydrophobic sequence (E12) as an efficient assembling function, were combined and incorporated into one molecule. The fusion protein, designated ERE-EGF, was produced in Escherichia coli and purified with affinity chromatography using a His-tag. The ERE-EGF coated on an unmodified hydrophobic surface of a cell-culture plate (through the hydrophobic E12 moiety) retained both cell adhesive activity (through the RGD sequence) and cell growth activity (through the EGF moiety).
