Chrd ELISA Kit (Rat) (OKBB01453)

Description of target: Chordin is a bone morphogenetic protein antagonist composed of four small cysteine-rich domains, whose function is not known. In humans, the chordin peptide is encoded by the CHRD gene. It is mapped to 11q23. It dorsalizes the developing embryo by binding ventralizing TGFβ proteins such as bone morphogenetic proteins. It may also play a role in organogenesis. In mice, Chordin is expressed in the node but not in the anterior visceral endoderm. It has been found to be required for forebrain development. In developing mice that are deficient in both chordin and noggin, the head is nearly absent. This is significant because when only noggin is deficient there are mild defects but the head still forms. Chordin is also involved in avian gastrulation. It is expressed in the anterior cells of Koller's sickle, which form the anterior cells of the primitive streak, a key structure through which gastrulation occurs.;Species reactivity: Rat;Application: ELISA;Assay info: ;Sensitivity: <50pg/ml
