Chordin is an organizer protein that regulates the formation of the dorsal-ventral axis during frog embryonic development. It inhibits BMP (bone morphogenetic protein) signaling, which is involved in ventralization. By inhibiting BMP signaling, chordin promotes the formation of the dorsal axis, which is necessary for the formation of the central nervous system. Therefore, removing chordin would most likely disrupt the determination of the central nervous system.
