Expressed in ventral anterior midbrain, cerebellum and ventral spinal chord

Expressed in telencephalon ventricular zone, ventral anterior midbrain, hindbrain rhombomeres (weak in rhombomere 3 and rhombomere 5), ventral anterior spinal chord, part of posterior branchial arches

Expressed in telencephalon ventricular zone, in anterior ventral diencephalon, dorsal diencephalon, anterior tectum, tegmentum, hindbrain, spinal chord, branchial arches, retina

Expressed in telencephalon ventricular zone, in anterior ventral diencephalon, dorsal diencephalon, anterior tectum, tegmentum, hindbrain, branchial arches

Expressed in telencephalon ventricular zone, in anterior ventral diencephalon, dorsal diencephalon, anterior tectum, tegmentum, hindbrain, branchial arches

Expressed in telencephalon ventricular zone, in anterior ventral diencephalon, dorsal diencephalon, anterior tectum, tegmentum, hindbrain, branchial arches, retina photoreceptor cell layer (weaker in inner nuclear layer)

Expressed in forebrain ventricular zone, pretectum, dorsal tegmentum, cerebellum, posterior tegmentum, ventral diencephalon, branchial arches
Please note that in 5 day old embryos some structures are not accessible to the probe (such as notochord, most of the trunk and tail). Therefore the description of the expression pattern is only partial.
