Secreted bone morphogenetic protein antagonists of the Chordin family
Chordin, Chordin-like 1, and Chordin-like 2 are secreted bone morphogenetic protein (BMP) antagonists with highly conserved Chordin-like cysteine-rich domains.Recently, Brorin and Brorin-like have been identified as new Chordin-like BMP antagonists.A Chordin ortholog, Short gastrulation, has been identified in Drosophila, a protostome, but not othe
