Figure 1From: Mitotic phosphorylation activates hepatoma-derived growth factor as a mitogenHDGF is a phosphoprotein. Autoradiogram of HDGF immunoprecipitated from COS-7 cells that transiently expressed wild type rat GFP-HDGF (WT-HDGF) or S103A, S165A, or S202A-HDGF substitution mutations after in vivo [32P] orthophosphate labeling for two hours, and resolution by SDS-PAGE.Back to article page
