Summaries
Gene Group (FlyBase)
RECEPTOR GUANYLATE CYCLASES -
Receptor guanylate cyclases are single-pass transmembrane receptors with an extracellular ligand-binding domain and intracellular guanylate cyclase and pseudokinase kinase domains. Ligand binding results in the activation of the intracellular guanylyl cyclase domain and the production of cyclic GMP from GTP. The kinase domain may have a regulatory role and may bind ATP. (Adapted from FBrf0228387).

Structure
Protein 3D structure   (Predicted by AlphaFold)   (AlphaFold entry Q07553)

If you don't see a structure in the viewer, refresh your browser.
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

Weak Gyc32E expression was observed in RNA from larvae and adult heads on northern blots. By in situ hybridization, transcripts are detected in ovaries in germarium regions 2 and 3. They disappear and then reappear at stage S10 in nurse cells. Gyc32E transcripts are uniform in very early embryos. Later they are confined to yolk and are not present in blastoderm cells. They reappear along the germ band of germ band elongated embryos.

    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.

    cDNA clones, fully sequenced
    BDGP DGC clones
      Other clones
        Drosophila Genomics Resource Center cDNA clones

        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.

                  dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.

                  Preliminary experiments using a P element-borne copy of the wild type Gyc32E 12kb genomic region failed to rescue either abo1 or l(2)gd11 phenotypes.

                  Identified as the first transcription unit downstream of the blood insertion in abo1.
