transcription factor - homeodomain - plays a critical role in restriction of the number of photoreceptor precursors in the specification of R8 photoreceptors - a bistable loop between senseless and rough locks in R8 fate

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

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).
Comment: maternally deposited
In addition to the wild type staining in receptor cells R2, R3, R4, and R5, additional staining is observed in the position of the mystery cell in the rhohs.sev line.

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.

A 5.8kb genomic fragment contains all the information required for normal ro expression and function. Important cis-regulatory sequences are located both in the 5' promoter region (between -940 and -340, coordinates from FBrf0047664) and a tissue-specific enhancer is located in the first intron. Amino acids located in the C-terminal region of the homeodomain play an important role in binding site recognition.
ro and gl gene products are required for B and B-H2 gene expression in R1 and R6.
Mutations in ro affect early ommatidia development.
Expression of ro in the presumptive R7 cell transforms the cell into an R1-6 type photoreceptor. The transformation is cell autonomous and depends on the presence of the sev gene. In wild type, ro may function autonomously in the specification of R2/5 photoreceptor identity but by itself may not initiate neural development.
Adult eyes are rough with irregular facet size and shape. Ommatidia irregular size and shape. The abnormal ro phenotype is due to a developmental defect: pattern formation defect.
Analysis of somatic mosaics suggests that the or gene function is required only in photoreceptors R2 and R5.
