transcription factor - homeodomain and pou domain - along with pdm-1 involved in cell fate determination of a subset of temporally determined neural subtypes - morphology of sensory neurons is diversified through a series of suppressive transcriptional interactions involving Pdm1 (Nubbin) and Pdm2, the homeodomain transcription factor Cut, and the transcriptional regulators Scalloped and Vestigial

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.
pdm2 transcript is expressed in cells surrounding the wing pouch, with higher expression levels observed in the anterior compartment. Expression is undetectable in the leg discs.
In cellular blastoderm stage embryos, pdm2 is expressed in a broad band from 20-40% egg length and at the dorsal tip of the embryo. This pattern is replace by a complicated pattern of stripes. After gastrulation, 14 stripes are observed, one per parasegment. In later embryos, expression is seen in a resticted set of cells in the CNS. Maximum levels of pdm2 RNA are observed between 4 and 12 hours of embryonic development on northern blots.
pdm2 transcripts are detected predominantly in 3-6 hr embryo RNA. They are expressed in the blastoderm embryo in a band of staining from 25-50% egg length and in an anterior cap. During gastrulation, a striped pattern is observed. Later pdm2 expression is observed in discrete subsets of neuroblasts in the developing CNS, in the brain, and in the hindgut.
pdm2 transcripts are first expressed in the cellular blastoderm stage in two broad stripes in the posterior half of the embryo. These develop into a complicated pattern of stripes. Expression is later seen along the neurectoderm and in a restricted set of cells of the CNS and PNS. Expression in the head region occurs in the optic lobe primordium, brain primordia, clypeolabrum, epiphysis, labral sense organ, and in the ventral ectodermal regions of the labial, maxillary, and mandibullary buds. pdm2 transcripts are present at maximal levels in 0-12 hr embryos and at much reduced levels at later stages.
pdm2 transcripts are expressed at high levels during the first 12 hours of embryogenesis and in 2nd instar larvae and are detectable in other stages at reduced levels. pdm2 expression is initially seen at the cellular blastoderm stage in two bands in parasegments 7 and 11. During gastrulation, expression is seen in an odd pair-rule pattern which later becomes a segment polarity pattern with alternating wide and narrow stripes. At stage 10, expression is seen in the neurogenic region with the exception of the midline. In germband extended embryos, expression is seen in selected neurons and their support cells. Expression is also seen in some lateral and dorsal clusters of PNS cells, in the ligament cells of the chordotonal organs, and in two types of neurons (bipolar dendrite neurons and dendritic arbor cells).

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.
Virtually all aspects of pdm2 RNA expression are conserved between D.melanogaster and D.virilis.
nub and pdm2 both contribute toward the development of a full complement of mature RP2 neurons by being expressed in and acting on ganglion mother cell 2a (GMC-2a), the RP2 progenitor cell. nub plays a quantitatively less important role than pdm2. nub and pdm2 act to specify GMC-2a cell identity and not merely act to positively regulate GMC-2a cell division. Within the hierarchy of genes expressed in GMC4-2a nub and pdm2 lie downstream of pros and ftz and upstream of eve.
pdm2 is required for segmentation and neurogenesis.
The genomic organisation and early embryonic expression pattern of pdm2 has been determined.
The pdm2 gene product specifies the cell fate of GMC-1 in the NB4-2 lineage. Its ectopic expression in the two progeny cells of GMC-1 is sufficient to cause both the cells to adopt a GMC-1 cell identity.
pdm2 is transcribed in elements of the developing nervous system suggesting a functional role in neurogenesis and neurospecification.
pdm2 contains a POU domain, and is expressed at maximum levels during early development.
The spatial expression pattern of pdm2 has been characterized.
