bs-70250R

DATASHEET

Host: Rabbit

Target Protein: Ribosomal protein S6 (Ser244)

Specificity: Specific for endogenous levels of the ~28 kDa rpS6 protein phosphorylated at Ser244. Immunolabeling is blocked by preadsorption with the phosphopeptide used as antigen, but not by the corresponding non-phosphopeptide.

Modification Site: Ser244

Clonality: Polyclonal

Isotype: IgG

Entrez Gene: 20104

Swiss Prot: P62754

Source: Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser244 of mouse rpS6, conjugated to keyhole limpet hemocyanin (KLH).

Purification: Antigen Affinity purification from Pooled whole antiserum

Storage Buffer: 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol.

Storage: Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Background:

Ribosomal protein S6 (rpS6) is a critical component of the 40 S ribosomal subunit that mediates translation initiation at the 5'-m7 GpppG cap of mRNA. The rpS6 protein is both cytoplasmic and nuclear localized (Chen and Dittmer 2011). In response to mitogenic stimuli, rpS6 undergoes ordered C-terminal phosphorylation by p70 S6 kinases and p90 ribosomal S6 kinases on four Ser residues (Ser-235, Ser-236, Ser-240, and Ser-244) whose modification potentiates rpS6 cap binding activity (Hutchinson et al., 2011). Additionally, rpS6 phosphorylation and function are highly regulated and have been implicated in the regulation of translational initiation and protein synthesis in response to extracellular stimuli such as TRAIL and gamma interferon (IFN-γ), as well as upon activation of the phosphatidylinositol 3-kinase (PI3K)–Akt–mTOR pathway (Chen and Dittmer 2011).
