:
The BRE containing promoter activity was stimulated by BMP-2 or by constitutively active BMP receptors ( BMPR-IA and BMPR-IB )

:
Reporter gene assays using Xenopus animal pole ectodermal explants ( animal caps ) revealed that this conserved 21 bp BRE is both necessary and sufficient for BMP responsiveness
