Détail du produit

Épitope: AA 456-465, pSer463, pSer465

Purification: The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

Immunogène: Phosphorylated Human Smad1 aa 456-465 Peptide

Isotype: IgG2a kappa

Information d'application

Protocole: In human PBMC, overnight serum starvation was found to be necessary for detection of a BMP-6-induced increase in Smad1/8 phosphorylation. Serum starvation for 1 hour following PBMC isolation was not sufficient to reduce basal levels of Smad1 (pS463/pS465)/Smad8(pS465/pS467). Some donor variation was observed in the reduction of basal phosphorylation by overnight serum starvation.

Détail du antigène

Antigène: Smad1 , Smad8

Sujet: The N6-1233 monoclonal antibody specifically binds to the Smad1 protein phosphorylated at the Ser463/465 sites and the Smad8 protein phosphorylated at the Ser465/467 sites. Smad1 and Smad8 are ~60 kDa proteins and are members of the Smad superfamily. The Smad family members are divided into three subfamilies: receptor regulated Smads or R-Smads, including Smads1, 2, 3, 5, and 8, common partner Smad, or Co-Smad, including Smad4, and inhibitory Smads, or I-Smad, including Smads 6 and 7. Activation of Transforming Growth Factor-beta (TGF-beta) superfamily serine/threonine kinase receptors, such as TGF-beta and Bone Morphogenic Protein (BMP) receptors, leads to the phosphorylation of R-Smads at several sites. It has been shown that Ser463 and Ser465 of Smad1 are phosphorylated by BMP receptors. In B cells and pre-B cells, BMP-6 has been shown to induce Smad1/5/8 phosphorylation and inhibit cell proliferation. Phosphorylated R-Smads form complexes with Co-Smad and translocate into the nucleus to regulate transcription affecting a wide range of critical processes including cell-fate determination, proliferation, morphogenesis, differentiation and apoptosis. The inhibitory Smads inhibit this pathway through two potential mechanisms: either by preventing R-Smads from binding to their corresponding receptors and/or by competing with Smad4, the Co-Smad, from binding to R-Smads. This antibody may crossreact with Smad5 pS463/pS465 based on sequence homology.
