The 14-3-3 family of conserved regulatory proteins is expressed in all eukaryotic cells and are encoded by seven genes in mammals. 14-3-3 proteins bind many types of signaling proteins, including kinases, phosphatases, and transmembrane receptors. More than 100 signaling proteins have been reported as 14-3-3 ligands. The name 14-3-3 refers to the particular elution and migration pattern of these proteins on DEAE-cellulose chromatography and starch-gel electrophoresis. Elevated amounts of 14-3-3 proteins are found in the cerebrospinal fluid of patients with Creutzfeldt-Jakob disease. 14-3-3-sigma, also known as stratifin, epithelial cell marker protein 1, HME1, and YWHAS, is regulated by p53 and plays a role in the G2-M-phase checkpoint.
These products are affinity-purified IgG antibodies that recognize human 14-3-3-sigma protein. The antibodies were raised in rabbit using synthetic peptides, and can be used for Western blot (WB) detection or immunohistochemical (IHC) detection of human 14-3-3-sigma protein.
