atl² increases BMP signaling in motor neurons. Representative confocal images of w¹¹¹⁸ (A) and atl² (B) motor neuron nuclei from third-instar larvae labeled with anti-pMad antibody. Scale bar: 10 µm. (C) Mean±s.e.m. pMad levels for w¹¹¹⁸, atl², atl²; arm>+, atl²; arm>atl⁺, atl²; OK6>+, and atl²; OK6>atl⁺ in motor neuron nuclei. Each scattergram data point is the average nuclear signal intensity per area for a single larva. P-values shown represent an unpaired Student's t-test performed with KaleidaGraph.
