Protocol
Available protocols: Immunofluorescence (Frozen), Immunofluorescence (Immunocytochemistry), Flow Cytometry (Fixed/Permeabilized)
Specificity / Sensitivity
S6 Ribosomal Protein (54D2) Mouse Monoclonal Antibody (Alexa Fluor
Species Reactivity: Human, Mouse, Rat, Monkey, D. melanogaster
Source / Purification
Monoclonal antibody is produced by immunizing animals with a recombinant fusion protein corresponding to full-length human S6 ribosomal protein. The epitope corresponds to a region surrounding Asp20 of human S6 ribosomal protein.
Background
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 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 S6 protein (4,5).
