Product Type Specific: RPS6 phosphosite-specific antibody
Antibody Code: PN1025
Antibody Target Type: Phosphosite-specific
Antibody Phosphosite: S240+S244
Protein UniProt: P62753
Protein SigNET: RPS6
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Synthetic phosphopeptide patterned after human RPS6
Antibody Immunogen Sequence: LRA(pS)TSK(pS)E(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues L237 to E245; in the C-terminus of the ribosomal protein. S235+S236+S240 phosphorylation is believed to increase the translation of mRNA important for protein synthesis by facilitating the assembly of the preinitiation complex. S240 and S244 are amongsr the major sites of in vivo phosphorylation of S6 based on ≥916 and ≥599 high throughput mass spectrometry reports, respectively, recorded in PhosphoSitePlus. These sites are phosphorylated by p70 S6K in vitro.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: RPS6 (Ribosomal protein S6; eS6) is a key 32–34 kDa component of the 40S ribosomal subunit in eukaryotes that plays a vital role in protein synthesis and translation regulation. It controls cell growth and proliferation through the selective translation of particular classes of mRNA that are important in protein synthesis. RPS6 is located in the small head region of the 40S subunit, at the interface with the 60S subunit. While it is a structural component of the ribosome, its phosphorylation is not required for general translation, but rather specifically affects the translation efficiency of specific mRNA classes Growth factor stimulation of cultured cells leads to stong phosphorylation of RPS6 at multiple sites located in its C-terminus (specifically serine residues 235, 236, 240, 244, and 247 in mammals), which enhances it translational activity. Phosphorylation is generally triggered by mitogenic stimuli, nutrients, and growth factors via the mTOR pathway. This phosphorylation may be mediated by several protein kinases including those in the p70 S6 kinase and RSK families. RPS6 acts as a regulator of cell size, proliferation, and glucose homeostasis.
