Xenopus organizer specific gene Noggin possesses nearly all the characterestic properties of the action of organizer to specify the embryonic body axis. To analyze how the maternal inherited factors control its expression pattern, we cloned the 5' regulatory region of noggin gene. The 1.5 kb upstream sequense could direct reporter gene to express in vivo and data from deletion analysis indicated that a 229 base pair fragmet is essential for activating noggin expression. We further demonstrated that the response elements within this regulatory region were indeed under the control of growth factor activin and Wnt signaling pathway components.
