Species: Human Expressing host: HEK293 cells Description: Recombinant Human CER1/DAND4 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Thr18-Ala267) of human CER1/DAND4 (Accession #NP_005445.1) fused with a 6His tag at the C-terminus. Tag: C-His Purity: > 95% by SDS-PAGE. Endotoxin: preparation: Lyophilized from a 0.22 m filtered solution of 25mM NaAc pH 7.4. Storage Store the lyophilized protein at -20C to -80C for 12 months.
After reconstitution, the protein solution is stable at -20C for 3 months, at 2-8C for up to 1 week.Unopened freeze-dried powder,Store at -20 to -80 °C for twelve months
Redissolution: Centrifuge the vial before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid votex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles.Redissolution:Store at -20 to -80 °C,avoid repeated freeze thaw cycles
Background Information : Cerberus 1, also called DAND4, is a member of the DAN domain family of BMP antagonists that includes DAN (DAND1), Gremlin/Drm (DAND2), PRDC (Protein Related to Dan and Cerberus; DAND3), and COCO/Dante (DAND5). DAN family members contain a cysteine-knot domain that is homologous to that found in other TGF-beta superfamily ligands. Mature human Cerberus 1 shares 67% and 68% amino acid (aa) sequence identity with mouse and rat Cerberus 1, respectively. Within the cysteine-knot domain, it shares 24%-37% aa sequence identity with mouse DAN, Gremlin, PRDC, and COCO. Cerberus 1 is a secreted 38 kDa glycoprotein that forms homodimers. Cerberus-S, which is generated by proteolysis in Xenopus, is a short version of the molecule and includes the C-terminal cysteine-knot domain. At the onset of gastrulation, Cerberus 1 is transiently expressed in anterior endodermal structures in response to Nodal and Shh . Cerberus 1 binds BMP-4 and Nodal and inhibits their activities. Xenopus Cerberus has also been shown to bind Xenopus Wnt8. These inhibitory functions of Cerberus favor mesodermal development in the anterior region of the gastrula and suppresses posterior mesodermal differentiation. In chick and Xenopus, Cerberus 1 also regulates, but is not required for embryonic left-right polarization, neurulation, and head and heart induction. GeneID 9350 Swiss Prot O95813 Alias: DAND4;CER1MedChemExpress (MCE) recombinant proteins include: cytokines, enzymes, growth factors, hormones, receptors, transcription factors, antibody fragments, etc. They are often essential for supporting cell growth, stimulating cell signaling pathways, triggering or inhibiting cell differentiation; and are useful tools for elucidating protein structure and function, understanding disease onset and progression, and validating pharmaceutical targets. At MedChemExpress (MCE), we strive to provide products with only the highest quality. Protein identity, purity and biological activity are assured by our robust quality control and assurance procedures.
