Gene Group (FlyBase)
C2H2 ZINC FINGER TRANSCRIPTION FACTORS -
Zinc finger C2H2 transcription factors are sequence-specific DNA binding proteins that regulate transcription. They possess DNA-binding domains that are formed from repeated Cys2His2 zinc finger motifs. (Adapted from PMID:1835093, FBrf0220103 and FBrf0155739).
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
l(2)49Fc
Embryonic lethal.
Summary (Interactive Fly)

zinc finger - required for specification of a subset of neurons - functions in regulating dendrite and axon development - necessary for the proper development of tracheal branches and dendritic branches of multidendritic neurons, as well as development of the R8 cell in eye development

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.

Comments on Gene Model

Complex/atypical overlap: Shares UTR sequences with upstream and downstream genes; shares portion of CDS with one isoform of upstream gene; for some isoforms internal coding exons correspond to UTR exons of other gene.

Genes with CDS overlap: minor isoform of Kdm4B appears to share coding sequence with seq (terminal coding exon of Kdm4B and initial coding exon of seq, 131 residues). Other Kdm4B isoforms are highly conserved; seq orthologs not found outside Drosophila.

Gene model reviewed during 5.47

Exons of Kdm4B, seq and CG17724 overlap.

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

The expression pattern of seq is highly dynamic in the eye disc in early differentiating R7 and R8 cells during the time of axon growth and medulla innervation. Expression in R8 tails off before expression in R7 is observed. By the time the R7 cell initiates axonal projection which is accompanied by a high level of seq, the axon of the neighboring R8 cell has already reached the medulla and seq expression has been turned off.

Protein is detected in embryos from stage 3/4 on in the nuclei of neurons and sheath cells of the developing nervous system. Pan-neural nuclear protein is also detected in the adult head including the photoreceptor cells.

          dsRNA has been made from templates generated with primers directed against this gene. seq RNAi results in overextension of ddaD and ddaE dendrites.

          seq mutants affect the cell fate decision of a small subset of neurons but have global effects on axon and dendrite morphologies of most and possibly all neurons.

          seq has a function in dendritic development.

          Annotation CG4037 split into CG33182, CG32904 (seq) and CG17724 in release 3 of the genome annotation.

          One or more of the processed transcripts for this gene share(s) untranslated sequences with a transcript of an adjacent gene, but encode(s) a single open reading frame (ORF). The non-overlapping ORFs that share untranslated sequences are represented by seq and CG17724.
