The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

dac-protein is expressed in the lamina and lobula plate anlage as well as in distal cells of the larval optic anlage.
There is no difference in the expression pattern of dac between the male and female prothoracic leg discs.
When it is first expressed in the prospective tarsus, dac abuts the B-H1 expression domain distally. Just before the central fold forms, a gap region devoid of either apears. By the prepupal stage, dac is expressed strongly in the presumptive metatarsus and moderately in presumptive tarsal segment 2.
dac is expressed in CCAP-EN neurons but not in the CCAP-IN neurons.
dac protein is not detected in the male germline.
Expression in procephalic neuroblasts stage 9-11: tritocerebrum - v2; protocerebrum - av1, cd1, cd2, cd4, cd6, cd8, cd9, cd14, cv7, cv9, pd1, pd8, pd11
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.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.

dac is essential for proper joint formation between antennal segment 5 and the arista.
dac plays sex-specific roles in the development of the genitalia.
dac has a function in the structural development of the mushroom body.
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.

Some mutant alleles produce escapers with crippled legs (hence the name "dachshund").
The gene is named "dachshund" after the mutant phenotype; mutant flies have short, little legs.
