摘要: Phosphorylation of a restricted number ribosomal proteins has been described for all eukaryotic cells analyzed to date. The actual phosphorylated varies, but single basic protein with Mr around 30,000 is the most prominent phosphoprotein in ribosomes (Wool, 1979; Cuny, 1985; Brathohn, 1986 ). In mammals up five phosphate groups can be incorporated into this protein, designated S6 (Thomas et al., 1980), and increased phosphorylation an apparent prerequisite activation synthesis response growth factors 1982).
