How both BMP and Wnt signalling pathways regulate lineage specification early in development is unclear. Here, the authors show that endoglin via Jdp2, an AP-1 family member, modulates BMP and Wnt signalling to commit mesodermal progenitors to a haematopoietic fate at the expense of the cardiac lineage.
