UAS regulatory sequences drive expression of Drer\nkx6.1.
Embryos expressing Brer\nkx6.1Scer\UAS.cCa under the control of Scer\GAL4sca.PU have thicker segmental B (SNb) motor nerves than normal.
Embryos expressing Brer\nkx6.1Scer\UAS.cCa under the control of Scer\GAL4sca.PU have a normal number of RP1, RP3, RP4 and RP5 neurons. The number of medial lateral motoneurons per hemisegment is normal in these embryos, but the number of lateral cluster motoneurons per hemisegment is increased compared to controls.
