The gene dachshund is referred to in FlyBase by the symbol Dmel\dac (CG4952, FBgn0005677). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: protein binding. There is experimental evidence that it is involved in the biological process: axon guidance; compound eye photoreceptor development; compound eye development; negative regulation of gene expression; neuron differentiation; mushroom body development; photoreceptor cell fate specification; antennal joint development; genital disc sexually dimorphic development. 67 alleles are reported. The phenotypes of these alleles are annotated with: organ system subdivision; adult segment; external compound sense organ; appendage segment; peripheral nervous system; imaginal precursor; integumentary specialisation; metathoracic metatarsus; cell part; mesothoracic femur; epithelial furrow.

Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderate expression to a trough of extremely low expression. Peak expression observed within 06-24 hour embryonic stages, during late larval stages, at stages throughout the pupal period. Summary of FlyAtlas Anatomical Expression Data: Expression at moderate levels in the following post-embryonic organs or tissues: larval/adult central nervous system, larval Malpighian tubules.

dac protein is expressed in a subset of neurons of the medulla anlage in third instar larva. In adults, dac is expressed in the medulla neurons Tm9, Dm8a and Dm8b.
dac protein is observed in mushroom body nuclei at 48, 72, and 96 hours after puparium formation. It is also evident in the area of the mushroom bodies in larvae at all stages and in embryos beginning at around stage 9. In adults, dac protein expression occurs in mushroom body neurons that are 8-10 hours old but not in neuroblasts, ganglion mother cells, or newly born neurons.
dac is expressed in a cluster of approximately 10-12 cells beginning at stage 9 of embryogenesis, which correspond to the mushroom body neuroblasts. Expression remains in the mushroom body ectoderm and mushroom body neuroblasts throughout embryogenesis. Expression expands to include a cluster of cells laterally adjacent to the mushroom body neuroectoderm, referred to as the 'para-MB neurectoderm'. At later stages of embryogenesis, expression is found in scattered groups of neurons in both the ventral nerve cord and brain, and other embryonic tissue. By stage 16 dac positive cells become incorporated into the brain. Levels of expression are noted to decline by embryogenesis stage 13.
dac protein is expressed in imaginal discs in larvae. In the eye disc, it is expressed strongly in the unpatterned epithelium preceding the morphogenetic furrow. Posterior to the furrow, dac protein is expressed primarily in R1, R6, and R7 as well as in cone cells. dac protein is expressed only in the part of the eye disc that will become the retina. In leg discs, it is expressed in a ring pattern from a very early stage. It is also expressed in the third antennal disc segment and in wing discs. dac protein is also expressed in the embryonic CNS and in the optic lobe of the larval brain.
Summary of FlyAtlas Anatomical Expression Data: Expression at moderate levels in the following post-embryonic organs or tissues: larval/adult central nervous system, larval Malpighian tubules.

The 5' eye enhancer region located in intron 8 is primarily regulated by ey, although this regulation also requires eya and so. By contrast, the 3' eye enhancer is regulated by a combination of eya, so and dpp signaling, but is not directly dependent upon ey.
dac is required autonomously within the mushroom body (MB) for three major aspects of MB cell differentiation; it is required for MB neurites to respect their normal neuropil borders, for axons to arrange themselves properly within the horizontal (β, β' and γ) lobes and for MB axons to be able to fill the α lobe neuropil properly.
Targeted expression of dac is sufficient to direct ectopic retinal development in a variety of tissues, including the adult head, thorax and legs. dac and ey induce the expression of each other and dac is required for ectopic retinal development driven by ey misexpression. Results suggest dac and ey are likely to function together in the control of retinal cell-fate specification at the early stages of eye development.
