Cerberus 1/DAND4 Protein(C-6His) (recombinant human)

Protein Construction: Recombinant Human Cerberus 1 is produced by our Mammalian expression system and the target gene encoding Thr18-Ala267 is expressed with a 6His tag at the C-terminus. Sequence: Thr18-Ala267. Fusion tag: C-6His Endotoxin: < 1.0 EU per µg as determined by the LAL method. Apparent Molecular Mass: 35-42 kDa. Protein function: Cerberus 1 is a secreted glycoprotein that forms disulfide-linked homodimers. It is a cytokine 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. 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. The 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. Protein function: Cytokine that may play a role in anterior neural induction and somite formation during embryogenesis in part through a BMP-inhibitory mechanism. Can regulate Nodal signaling during gastrulation as well as the formation and patterning of the primitive streak. [The UniProt Consortium]
