Hyperactive BMP signaling induced by ALK2R206H requires type II receptor function in a Drosophila model for classic fibrodysplasia ossificans progressiva



Overexpression of human GATA4 in the Drosophila eyes through the GMR-GAL4 driver. All flies show narrow eyes. The original photograph has been duplicated for esthetic purposes to create 6 panels. From Amodio et al., Developmental Dynamics 241:205-213, 2012.
