Western Blotting
Western blot analysis of extracts from 293, NIH/3T3 and C6 cells, treated with λ phosphatase or 20% serum (20 min) as indicated, using Phospho-S6 Ribosomal Protein (Ser240/244) (61H9) Rabbit mAb (upper), or S6 Ribosomal Protein (5G10) Rabbit mAb #2217 (lower).
Flow Cytometry
Flow cytometric analysis of Jurkat cells, untreated (green), or LY294002, Wortmannin and U0126-treated (blue), using Phospho-S6 Ribosomal Protein (Ser240/244) (61H9) Rabbit mAb compared to a nonspecific negative control antibody (red).
IF-IC
Confocal immunofluorescent analysis of HeLa cells, LY294002-treated (left) or 20% serum-treated (right), using Phospho-S6 Ribosomal Protein (Ser240/244) (61H9) Rabbit mAb (green). Actin filaments have been labeled with Alexa Fluor® 555 phalloidin (red). Blue pseudocolor = DRAQ5™ (fluorescent DNA dye).
One way that growth factors and mitogens effectively promote sustained cell growth and proliferation is by upregulating mRNA translation (1,2). Growth factors and mitogens induce the activation of p70 S6 kinase and the subsequent phosphorylation of the S6 ribosomal protein. Phosphorylation of S6 ribosomal protein correlates with an increase in translation of mRNA transcripts that contain an oligopyrimidine tract in their 5' untranslated regions (2). These particular mRNA transcripts (5'TOP) encode proteins involved in cell cycle progression as well as ribosomal proteins and elongation factors necessary for translation (2,3). Important S6 ribosomal protein phosphorylation sites include several residues (Ser235, Ser236, Ser240 and Ser244) located within a small, carboxy-terminal region of the S6 protein (4,5).
