Anti-14-3-3 beta Antibody (Mouse Monoclonal antibody) General Information
Anti-14-3-3 beta Antibody
Reacts with: Human
Human 14-3-3 beta Has cross-reactivity in ELISA with Cynomolgus YWHAB No cross activity in ELISA with E.coli cell lysate (BL21 cell line)
Recombinant Human 14-3-3 beta / YWHAB protein (Catalog#10843-H09E)
This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, recombinant Human 14-3-3 beta / YWHAB (rh 14-3-3 beta / YWHAB; Catalog#10843-H09E; NP_003395.1; Met1-Asn246). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.
Monoclonal Mouse IgG2b Clone #03
0.2 μm filtered solution in PBS

Immunofluorescence staining of Human YWHAB in MCF7 cells. Cells were fixed with 4% PFA, blocked with 10% serum, and incubated with Mouse anti-Human YWHAB monoclonal antibody (1:60) at 4℃ overnight. Then cells were stained with the Alexa Fluor® 488-conjugated Goat Anti-mouse IgG secondary antibody (green) and counterstained with DAPI (blue). Positive staining was localized to cytoplasm.
Flow cytometric analysis of Human YWHAB expression on Molt-4 cells. The cells were treated according to manufacturer’s manual (BD Pharmingen™ Cat. No. 554714), stained with purified anti-Human YWHAB, then a FITC-conjugated second step antibody. The fluorescence histograms were derived from gated events with the forward and side light-scatter characteristics of intact cells.
14-3-3 beta / YWHAB is a member of the 14-3-3 proteins family. 14-3-3 proteins are a group of highly conserved proteins that are involved in many vital cellular processes such as metabolism, protein trafficking, signal transduction, apoptosis and cell cycle regulation. 14-3-3 proteins are mainly localized in the synapses and neuronal cytoplasm, and seven isoforms have been identified in mammals. This family of proteins was initially identified as adaptor proteins which bind to phosphoserine-containing motifs. Binding motifs and potential functions of 14-3-3 proteins are now recognized to have a wide range of functional relevance. 14-3-3 beta / YWHAB is found in both plants and mammals, and this protein is 1% identical to the mouse ortholog. 14-3-3 beta / YWHAB interacts with CDC25 phosphatases, RAF1 and IRS1 proteins, suggesting its role in diverse biochemical activities related to signal transduction, such as cell division and regulation of insulin sensitivity. 14-3-3 beta / YWHAB has also been implicated in the pathogenesis of small cell lung cancer. 14-3-3 beta / YWHAB binding negatively regulates RSK1 activity to maintain signal specificity and that association/dissociation of the 14-3-3beta-RSK1 complex is likely to be important for mitogen-mediated RSK1 activation.
