Specific isoforms of Drosophila shroom define spatial requirements for the induction of apical constriction



The Drosophila Shroom protein, dShrmA, induces apical constriction when ectopically expressed in the embryonic ectoderm. An embryo expressing dShrmA in the dorsal ectoderm was stained to detect dShrm (green) and F-actin (red). Inset shows a scanning electron micrograph of a similar staged embryo also expressing dShrmA in the dorsal ectoderm. From Bolinger et al., Developmental Dynamics 239:2078–2093, 2010.
