Recombinant protein corresponding to human 14-3-3 sigma protein. Cellular Localization: Cytoplasmic.
14-3-3 proteins are 30kD polypeptides with nine closely related members in mammals. They are also found in plants and fungi. 14-3-3 proteins are a family of small, widely expressed, highly conserved cytosolic proteins which bind to and influence the activities of a diverse group of molecules involved in signal transduction, cell cycle regulation and apoptosis, including Raf, PKC, Bad, Cbl, and c-Bcr. Interactions between 14-3-3 and target proteins are strongly influenced by the phosphorylation state of 14-3-3 and the target protein. 14-3-3 proteins form homo- and heterodimeric cup-like structures that bind to discrete phosphoserine-containing motifs. In some instances, 14-3-3 proteins appear to export their binding partners from the nucleus to the cytoplasm in a phosphorylation and Crm1-dependent manner. 14-3-3 sigma shares cyclin-Cdk2 binding motifs with different cell cycle regulators, including p107, p130, p21Cip1, p27Kip1 and p57Kip2 and is associated with cyclin-Cdk complexes in vitro and in vivo. Expression of 14-3-3 sigma is higher in normal epithelial cells. Applications: Suitable for use in Immunofluorescence, Immunoprecipitation, Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilutions: Immunohistochemistry (Formalin/paraffin): Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 minutes followed by cooling at RT for 20 minutes. Optimal dilutions to be determined by the researcher. Positive Control: HT29 cells, Skin Storage and Stability: Store product at 4C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20C. Aliquots are stable at -20C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Note: Sodium azide is a potent inhibitor of peroxidase and should not be added to HRP conjugates. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Note: Applications are based on unconjugated antibody.
