Background:
Embryonic stem cells can maintain a pluripotent state that is controlled by a set of transcription factors that include Oct-4, Sox2, and Nanog. Chromatin immunoprecipitation experiments show that Sox2 and Oct-4 bind to thousands of gene regulatory sites, many of which regulate cell pluripotency and early embryonic development. siRNA knockdown of either Sox2 or Oct-4 results in loss of pluripotency, while overexpression of Oct-4 and Sox2, along with additional transcription factors Klf4 and c-Myc, can reprogram somatic cells to a pluripotent state. Sox2 also regulates adult multipotent progenitors in various epithelial tissues, and may be important for survival and regeneration of these tissues. The activity of Sox2 may be regulated by phosphorylation and methylation. Akt1 phosphorylates Thr-118 and enhances Sox2 transcriptional activity, while Set7 can monomethylate Lys-119 leading to inhibition of Sox2 transcriptional activity, as well as Sox2 ubiquination and degradation.

Sequence: Unphosphorylated Sox2 (Thr-118) synthetic peptide corresponding to amino acids surrounding Thr-118 in mouse Sox2. This site is well conserved in rat and human Sox2, and has high homology with the conserved site in Sox1 (Thr-126) and Sox3 (Thr-144), but low homology to other Sox family members.
Specificity: The peptide is an unphosphorylated control peptide for SX5525. The peptide is recommended for use in ELISA and for blocking antibody reactivity in western blot and immunocytochemistry.
Buffer/Storage:
Blocking Peptide is supplied in 50µl phosphate-buffered saline and 0.05% sodium azide. Store at –20°C. Stable for 1 year.
