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).

Expression assayed at stages 9, 11, 13, and 17. Expression may be continuous between assayed stages in some tissues.
Expression of transcript is observed throughout the developing neuroectoderm. Expression is lost in delaminated neuroblasts. While transcript is ubiquitous in the neuroectoderm it is not uniform. In stage 12 embryos transcript can be detected in some cells of the central and peripheral nervous system.

SoxN is expressed in all T4/T5 neuron subtypes, but not in their progenitors or in C/T neurons.
SoxN is expressed in the H-cell and H-cell sib at embryo stage 11 until the end of stage 13. Expression in the H-cell remains on through the end of embryogenesis.
SoxN protein is expressed throughout the ventral ectoderm from embryonic stage 5 to late stage 8. From stage 9 on, the protein decays. At stage 9 it is present in the entire epithelium, with the exception of the wg expression domain. After stage 9, protein expression further decays. From early stage 12 onwards, expression is reinitiated in segmental stripes of 6-cell width at the lateral periphery of the ventral epidermis. The stripes then expand along the dorsoventral axis and, from stage 13 onwards, span the ventral epidermis. SoxN continues to be expressed in 6-cell-wide stripes until the end of embyrogenesis. During the embryonic stages in which epidermal cell fate is determined, SoxN expression is restricted to the cells that will differentiate to produce denticles. In addition, SoxN protein and D protein were shown to co-localize in the ventral epidermis from stage 12 until the end of embryogenesis.
SoxN proteinexpression largely overlaps the transcript expression in stage 8-10 developing embryos, with expression in the neuroectoderm and absent or strongly reduced in delaminating neuroblasts.
In the third instar larval antennal disc, SoxN is expressed in three stripes of cells in the part of the disc that will give rise to the to antennal segments 2 and 3. In the eye disc, SoxN is expressed in differentiated photoreceptor cells posterior to the morphogenetic furrow. In the leg discs, SoxN is expressed in a few cells in the center of the disc, and in two lateral patches in the dorsal/posterior and ventral/anterior quadrants. SoxN is also expressed in neuroblasts of the optic proliferation centers and central brain, and in thoracic and abdominal neuroblasts.

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.
The sumoylation of the SoxN product regulates its activity in vivo.
One of 42 Drosophila genes identified as being most likely to reveal molecular and cellular mechanisms of nervous system development or plasticity relevant to human Mental Retardation disorders.
Loss of function mutations in SoxN result in a severe reduction in neuroblasts in the lateral and intermediate regions of the central nervous system, whereas ventral neuroblast formation is almost normal.
