Gene Summary
Transcription factor which is a downstream target of gcm and repo. Directly or indirectly activates the transcription of locos and pros, which are essential for the development of some glial cells. Plays an essential role in defining the cell shape and migration characteristics of longitudinal glia that enable them to establish a normal axon scaffold. (UniProt, Q24573)

A-T RICH INTERACTION DOMAIN TRANSCRIPTION FACTORS -
The A-T Rich Interaction Domain (ARID) transcription factors are sequence specific DNA-binding proteins that regulate transcription. The ARID-domain containing proteins contact DNA through the variant helix-turn-helix motif and hairpin structure. (Adapted from FBrf0146923 and FBrf0112110).
Protein Function (UniProtKB)
Transcription factor which is a downstream target of gcm and repo. Directly or indirectly activates the transcription of locos and pros, which are essential for the development of some glial cells. Plays an essential role in defining the cell shape and migration characteristics of longitudinal glia that enable them to establish a normal axon scaffold.
(UniProt, Q24573)
Summary (Interactive Fly)

transcription factor - ARID domain protein - required for proper patterning of the abdomen - necessary for neuronal pathfinding, female receptivity and repression of fruitless independent male courtship behaviors.

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Testis-specificity index

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).

Additional Descriptive Data

dri transcripts are expressed in a dynamic pattern during embryogenesis. They are distributed throughout the embryo during syncytial cleavage stages and at cellularization, are distributed in broad bands at the termini and in the center of the embryo. At germ band extension, the transcripts are found predominantly in the mesoderm and at later stages, are detected in the pharyngeal muscles, the amnioserosa, and in a distinct row of cells in the hindgut. They are also observed in the ring gland, in the clypeolabrum, in a ring of cells around the hindgut-midgut junction, and in several cells in each brain lobe. Ventrally, expression is observed in the salivary ducts, in a ring of cells at the foregut-midgut junction and in a repeated pattern in the CNS.

Additional Descriptive Data

dri protein is expressed in a dynamic pattern during embryogenesis. It is distributed evenly in syncytial nuclei and in contrast to the RNA is also uniformly distributed in late blastoderm embryos. At germ band extension, dri protein is found predominantly in the mesoderm. At later stages, protein is detected in the pharyngeal muscles, the amnioserosa, and in a distinct row of cells in the hindgut. It is also observed in the ring gland, clypeolabrum, a ring of cells around the hindgut-midgut junction, and several cells in each brain lobe. Ventrally, expression is observed in the salivary ducts, a ring of cells at the foregut-midgut junction and in a repeated pattern in the CNS.

                retn is required for positioning of the longitudinal glia in the embryonic central nervous system.

                retn is essential for anterior-posterior patterning and for muscle development in the embryo.

                Identification: Enhancer trap expression pattern survey for loci expressed in the ring gland.

                retn has been cloned and sequenced, and its expression pattern has been analysed.

                Identified in a screen for clones which bind an en homeodomain binding site.

                Mutations at the retn locus cause defects in midoogenesis.
